This story comes to my mind.

A pizzeria owner made money buying his own $24 pizzas from DoorDash for $16

      They could have made another $5 per 10 pizzas after order #1 by just delivering the pizza to themselves and sending the same boxes back out in the next delivery, and so on.

        An actual DoorDash driver had to do the delivery though. So you risk being reported and also, if they take awhile, pizza gets cold.

        But they also could have just raised prices on everything but the cheap one DoorDash was using for pricing.

          Risk being reported? To the company that you don't want interacting with you anyhow?

        • bruce511 3 days ago

          No, he means recycling the boxes not the pizza inside the box.

          The pizza itself can be literally given away (although if not on the premises, then presumably a box would be required.)

          I mean you can just have a silicone mold in there, no actual pizza required.

      Maybe that's my EU mindset, but I'm baffled how it's even legal to add a company to your public listing - complete with fake phone number - and just declare they're taking deliveries, all against the explicit wishes of the company.

      (Complete with "chill bro, I was just <s>joking</s>demand testing you" at the end)

      The blogger calls this being "tricked" to sign up for DoorDash. Seems to me, this is the same way a burglar "tricks" you into giving them your valuables.

        I can baffle you even more: if you register your company in Delaware, you don't even need to specify who owns the company.

        You only need to specify the name and address of the registered agent, which is sort of a "contact person", not somebody who works for the company.

      • Majromax 3 days ago

        It could be a trademark violation, even in the US, under the argument that DoorDash was “passing itself off” as the infringed-upon company. However, DoorDash would then argue that it was being honest – it was genuinely delivering authentic goods. It could violate trademark no more than a convenience store violates a trademark by correctly claiming it sells Coca-Cola.

    If you want to fight the VCs, you have to pull stunts like this. If they want to destroy local infrastructure because "free market", in an attempt to secure monopolies for themselves, then let them operate in a free market.

    • PaulDavisThe1st 4 days ago

        I said what I meant: most VC-backed startups could not survive in a real-world environment. Thank you for highlighting the distinction. Note that a free market isn't necessarily an unregulated market (see: Adam Smith).

        Personally, I don't believe that free markets are a sensible way to manage local affairs. They work well on a medium scale, where goods are fungible and efficiency matters: but for something like the local pizza place, customer behaviour doesn't match that of a market participant. I don't think it's sensible to expect the local pizza place to be free of arbitrage opportunities. Someone who identifies and exploits such opportunities (e.g. "free meals available on request") would be taking advantage of goodwill, and the reason we can't have nice things. However, if a large corpo comes along and starts trying to undercut the locals, absolutely mug them for all they're worth: they're playing a different game, and it's not one you should want them to win.

          I'm not sure why you think that. "Market participant" doesn't mean "always takes the lowest priced deal". People are willing to pay higher prices for food from local restaurants, as opposed to chains, fast food, etc., because they feel that the extra value they are getting (better quality, knowing the people who make the food, the atmosphere of the restaurant, etc.) is worth it. That's a free market.

          What is not a free market is large corporations who get all kinds of government favors to prop them up coming in and taking advantage of arbitrage opportunities that the locals don't have the time or the energy to protect against--still more if such opportunities involve "marketing" the locals' products in ways the locals didn't agree to, and would not agree to if they were given the opportunity to make a choice. I completely agree with you that such things should be shut down.

            A bit of a tangent, but price transparency is another factor.

            At least when economists publish their "it's the bestest and most efficient option" analyses their definition involves perfect information: No secret prices, no non-disclosure agreements, everybody knows what was paid for inputs and labor, etc.

            I bring this up because there is an unavoidable conflict between "the market that moves freely as a whole" version versus "the market where I'm free to keep secrets."

            • datsci_est_2015 3 days ago

              When the market does something I consider good, I call it free. When the market does something I consider bad, I call it not free [and it’s the government’s fault].

              Feels tangentially related to the No True Scotsman fallacy, but with the premise flipped?

            The change is that standardization of laws and limits to interstate commerce has made everything a national market.

            It doesn’t benefit the market to make plumbing contracting a national business, for example.

    • mattmaroon 3 days ago

      But why do you think they’re harming “local infrastructure”? The food delivery services didn’t hurt anything but their investors in the end. And they kept the restaurant industry alive during the pandemic, the fallout would have been so much worse. I work in the industry and know several bar/restaurant owners who will tell you DoorDash and competitors are the only reason they made it through 2020-21.

      Early on they stopped prohibiting restaurants from upcharging, so restaurants all did. They ended up with some extra sales and profits. The customer got VC funded free delivery.

      Enough alternatives kept the market place efficient. DoorDash can’t get too abusive when UberEats and Instacart are competing, restaurants have no switching cost.

      The whole thing worked for basically everyone involved except maybe the investors (DoorDash has significantly underperformed the S&P since it debuted on the market.)

        This has not been my experience.

        From my side, as someone old enough to remember Domino's running the "there in thirty minutes or it's free" promotions... These delivery services absolutely tanked the quality of delivery.

        Now you can basically only get slow delivery of over priced, cold food. Sure, you can get it from far more places, but it's a pyrrhic victory if I've ever seen one.

        Used to be if a restaurant offered delivery, it was ok food for delivery, at ok prices, and their drivers had gear to keep it warm and presentable.

        Now we basically only do pick up because these universal delivery companies suck at the one fucking thing they're supposed to do. But they've run all the local restaurants out of the delivery game.

        • heavenlyblue a day ago

          Yard Sale Pizza in London does it's own delivery and it's great where it's available. I hated that I had to use their website but delivery is always good and still warm.

      • hattmall 3 days ago

        Yeah, as someone else pointed out, the gig-delivery services killed the delivery industry. Sure I can get food from a bunch of shitty fast food places now, but deliveries are way more expensive and take forever. The only place that still does good delivery around me is Jimmy Johns and Dominoes. I used to have 15-20 good quality delivery places that were fast with free delivery. And I'm as talking on the phone averse as anyone but calling a delivery place was just easier than using an app and they could give you updates on when they were out of something or whatever.

        Uber eats / Door Dash suck so much I have no desire to order delivery food at all other than the two that run their own delivery and I know it will be a consistent experience. Anything else I either pick it or go without.

        It was also shady how they paid for ads to supplant the phone numbers on Google so you were calling Door dash instead of the food place.

          > Uber eats / Door Dash suck so much I have no desire to order delivery food at all other than the two that run their own delivery and I know it will be a consistent experience.

          Same. It’s about the only reason why I order from Dominos occasionally. But last week it got delivered by Uber even though I ordered directly on their website. It also took 45 minutes to get delivered instead of the usual 10. So now the only Uber-free delivery I can get is a Japanese restaurant.

          • mattmaroon 3 days ago

            Dominos lets people order from Uber Eats but still handles delivery itself. Maybe they fall back to Uber drivers when they are short staffed.

            I don’t know of any restaurants that previously had delivery of their own and switched. I’m sure they exist but it’s vanishingly small, for the reasons outlined.

            So all DoorDash does is give you the consumer more options. If you don’t like it, you don’t use it and nobody is harmed.

            Only a small percent of restaurants delivered in the first place outside of the ones like pizza that still do.

            • kergonath a day ago

              > Dominos lets people order from Uber Eats but still handles delivery itself. Maybe they fall back to Uber drivers when they are short staffed.

              Yes, I assume that this is what happened.

              > I don’t know of any restaurants that previously had delivery of their own and switched. I’m sure they exist but it’s vanishingly small, for the reasons outlined.

              I know a couple. But the reason why none of the pizza places around here do delivery (apart from Domino's, usually) is not that they stopped doing it. It's that these businesses have a relatively short life expectancy, and the ones that open don't have drivers and instead rely on Uber or equivalent. And I really mean that no pizza place handles delivery themselves. I checked. Quite thoroughly. Some Asian restaurants do have drivers but even then, it's not a given.

              > So all DoorDash does is give you the consumer more options. If you don’t like it, you don’t use it and nobody is harmed.

              The option is Uber, Deliveroo, or walking to the place (driving there is not practical because of the limited parking space). The result is that we do it less often and when we do it it's more expensive or cumbersome. I am willing to accept that it's different where you live but here the days of free delivery are mostly over.

              Used to be that just about every chinese food and pizza place would deliver. Now it's all gig app BS unless it's a massive order.

        • krisoft 3 days ago

          > calling a delivery place was just easier than using an app

          This is so much the polar opposite for me.

          First of all: restaurant discovery. With a phone interface you have to somehow out of band learn that there is a place who delivers to you, that they are open and obtain their menu. With an app no matter where you are it gives you a list of places which are open and deliver to you.

          Second is that you have all the time to browse the menu, do your research, contemplate, hand a phone around among many people, see your order, check your order, change your order, change your mind mid order. With a phone call a fast talking rushed person who often doesn’t speak the language natively talks to you from a noisy kitchen. And they expect you to get on with it fast because you are holding up the line. You better already know what you are ordering and be ready to make decisions about any substitutions as they come up.

          Then comes the payment. With apps I’m only trusting my payment details to a large company who has the engineering resources to make the transaction secure. With a phone order you either pay to the delivery driver (does he accept card? Do i have enough cash if not?) or you read in your card details to the phone. Which is just bonkers unsecure on so many levels.

          Then comes the tracking: with the app i see when the food is ready, and where the driver is in the delivery with a continously updated ETA. With a phone? You can call them again if the food does not show up I guess. Good luck.

          Then comes the handover. With the phone if the food was pre-paid the delivery driver just gives the food to whomever. If it is paid on delivery they give it to whomever pays them. Hope it reaches you. With the apps i’m using the app displays a one time code which the driver ask for to check that you are who ordered.

          Every element of the experience is better with an app in my opinion.

          > and they could give you updates on when they were out of something

          So can they through the app. But instead of telling every single costumer about what they are out of they just click it once on their admin and the items in question are stricken through in the menu. I see that all the time.

        DoorDash finds a way to consistently screw up orders.

        Order A,B,C - receive only A+B, or A,B,D. No explanation. Tipped generously.

        For a long time, I myself drove and picked up my orders. The same restaurants rarely made mistakes. I never had to ask for missing item to be included. They always had everything in the bag.

        It’s happened so often, it has to be malice from one of the parties involved.

                It's a collective action problem: it can't be solved by individuals like this. All you'll achieve is complicity in wage theft. A viable approach might be to prefer doing business with companies who promise their workers a good wage, but this requires that your local businesses actually make that commitment. To get that, you'll have to go outside the abstraction of the market, and actually talk to decisionmakers within the businesses. (This is sometimes called "activism".)

      • tjchear 3 days ago

        My understanding is food delivery companies take a huge cut (like 30%) so restaurants are forced to raise their prices significantly or risk losing customers. Even with that cut, food delivery customers still have to pay a significant delivery/service fee.

  • Spooky23 3 days ago

    A friend of mine did this, and had the food delivered to himself.

I feel I should point out that USPS has a lower rate for postcards (currently $0.61), so the threshold might be a bit lower.

I know that this is tongue-in-cheek and would be pretty funny to receive, but it isn't an apples-to-apples comparison. The experience of getting a little message printed on receipt paper is nothing like the experience of receiving a note or card in the mail. Through the mail you receive something physically from someone with their handwriting and some personality to it. Getting the Amazon message is more like printing out a text message on crummy paper.

Also, I don't have Prime, so it definitely isn't cost competitive for me anyway.

  • hatthew 4 days ago

    I agree in general, but as a one-off thing I'd very much enjoy getting a lime with a message saying "this was cheaper than sending a letter myself"

    • hoistbypetard 4 days ago

      I've started sending paperbacks instead of greeting cards when someone I know needs a get-well-soon card. In stores around here, greeting cards are often $7ish + postage. I can frequently ship a paperback with a gift receipt for $5 total. I include a gift message on the gift receipt, and choose a book I think someone might like to read while they're out of commission.

      I guess it's a bit like postal arbitrage, if I accept the cost of greeting cards themselves as part of the cost of the activity.

      To the extent that anyone has commented much, those who have commented had very positive reactions to what amounts to a book recommendation and a copy of the book I'm recommending along with a little note.

      • tempestn 3 days ago

        Haven't done it in a long time, but years ago I had a similar realization that picture frames were cheaper than cards. So you can frame a little note, either with a picture or just suggest they can reuse it if they like. Buying greeting cards always felt like kind of a waste. Lately our kids' schools have been doing a thing each year where the kids do some art and then you can buy cards (and other things) with it, so we've been using those as they're at least a bit personal. Once that's done, maybe I'll give picture frames again (or paperbacks or cans of tomato soup...)

      Letter, no. 61 cents is the post card rate, so you can send a post card thousands of miles for that. If you introduce an outside envelope its 78 cents to mail that thousands of miles, up to 1oz.

      afaik PostNL has to make a profit and the USPS can operate at a loss.

      Classic Dutch privatization

      • systemtest 3 days ago

        PostNL is a private company that used to be government owned. PostNL currently operates at a loss for mail delivery. They are mandated by law to deliver mail and that is something they can't get out of. There is not a maximum what PostNL can ask for stamps but the ACM (Authority Consumer & Market) can step in if they raise prices too much.

        So it appears to be privatised but with strict government regulations.

        https://climate.mit.edu/explainers/freight-transportation

        > While nearly three-quarters of the world’s cargo is carried by ocean-going ships, road vehicles like trucks and vans make up the majority, 65%, of freight’s emissions. Most ships burn fossil fuels and emit carbon, but they carry large amounts of freight at the same time, making them the most efficient way to move cargo. Road freight, however, can emit more than 100 times as much CO2 as ships to carry the same amount of freight the same distance. Road transport is also a fast-growing sector—80% of the global increase in diesel consumption can be attributed to trucks. E-commerce and home delivery are two reasons for this growth.

            Not just efficiency but you can use electric trains if your tracks are electrified. Add into that electricity production system that is mostly renewable+nuclear (the Nordics for example) and you get very very low emissions.

            classic volume grows faster than surface area.

            also, fuel is a huge cost (maybe even the main cost), and drag has a >linear relationship with speed- so the ships will slow down based on fuel prices.

        The distance from Shenzhen to Long Beach is some 300 times the distance from Long Beach to Pasadena, depending on where exactly in Pasadena and which route you take. The CO2 emissions factor for a truck is some 10-100x that of a container ship. The exact ratio depends on what kind of truck, and what scope of emissions are being included. The more one accounts for, the more it will favor the boat. But overall, the emissions from the oceanic leg of the trip are probably anywhere from 1-3x those of the truck.

        Shipping accounts for 80% of all international transport but only 37% of transport's carbon emissions (9:13 - 9:18).

        Road transport is highlighted as the "King of pollution," making up less than 10% of international transport but over half of emissions (9:26 - 9:32).

        Ferrying pears across the Earth is actually less carbon intensive than driving them in a truck to a packing plant across one's own country (9:48 - 9:52).

        All international shipping combined is responsible for only 2.5% of global emissions (9:58 - 10:15).

        I did some napkin math on this as I recently picked up a 3D Printer and wondered the environmental comparison to print-at-home vs pick something up at the store and I was surprised. Had some help from Claude but "last mile delivery" is absolutely where the majority of the kWh is burned in the supply chain.

        Container ships use ~0.015 kWh per ton-km[1] and a car is ~1.35 kWh/km.

        If you go to the store and end up getting >10 things it becomes "worth it" from an energy standpoint. Anything less printing at home seemed to be more economical... Not an expert though just saying it opened my eyes to how inefficient "last mile delivery" energy consumption is.

          > In 2022, researchers from the University of Michigan and Ford Motor Co. modeled a single 36-item grocery cart to compare greenhouse emissions from an e-commerce grocery delivery and a traditional trip to the store to get the same items. Gregory Keoleian and colleagues at the university's Center for Sustainable Systems found that using an electric vehicle to pick up groceries could cut emissions by as much as half, compared to a gas-powered vehicle.

          > They also found that home delivery could be an even better option. That's because with a delivery vehicle, orders are often clustered, with a driver dropping off not just your groceries, but also hitting neighbors during the same run. "Delivery is actually going to be more efficient in general than driving yourself in a gasoline SUV to the store to pick up your groceries," Keoleian says.

            So the EPA report is bullshit interpretation of the USDA study: >A recent USDA survey found that in 88% of U.S households, people hop in their car to buy groceries, driving an average of 4 miles to their preferred store.2

            USDA study: >Overall, households are, on average, 2.2 miles from the nearest SNAP-authorized supermarket or supercenter, but their usual store is 3.8 miles away.

            Based on these questions: >This report presents initial findings from the FoodAPS survey on three key questions:

            1. How do shoppers travel to their main store and how far do they travel to get there?

            2. In what type of store (eg., supermarket, mass merchandiser, convenience store) do U.S. households typically shop for groceries?

            3. Do store and travel mode differ by participation in food assistance programs or food security status?

            This can only tell us the distance to the store and does not support "All these car trips result in carbon pollution: over 17 million metric tons of CO2 come from car tailpipes just from driving back and forth to the grocery store."

            In order to draw that conclusion, you need to show that the travel to and from grocery store was single purpose. Which is not supported by the data.

            Most people I know don't go out of their way to go grocery shopping nor do they take specific trips to do so. It will be done in conjunction with another outing or when returning from work.

            This could also! explain the reason that food secure people travel greater distance, as they tend to travel greater distance overall they choose a location closer to their travel route rather than their dwelling.

        If the goal is reducing carbon emissions, making shipping emit half as much (650 Megatonne to 325 Mt) would be less of a gain than making trucking emit only 80% of its carbon (2,230 Mt to 1,830 Mt).

        The question is which is easier to do (ROI)... to cut the shipping fuel carbon footprint by half, or over the road trucking (that's about 1/4th of all the shipping) by 20%? For that matter, moving 25% of the over the road trucking to rail would accomplish that too.

In Poland, OLX (basically equivalent eBay) commonly has promotional campaigns, where you can buy something from a select category with 1 PLN shipping to box machine (around $0.30).

So people figured out, that you can abuse it to send anything to anyone in the country. Just create a fake listing for 1 PLN, let the receiver "buy" it (there is some extra service fee, but like $1) and there you go - probably the cheapest shipping possible, much cheaper than regular ~$5-7 box machine package.

TrackerFF 3 days ago

I used to import a lot of stuff from the US to Norway. I lived all the way up in northern Norway, so parcels would take roughly 5 working days from Oslo to where I lived.

Domestic overnight mail / express mail was prohibitively expensive, something equivalent to $150 for small items.

However, if I ordered something via USPS International Express, those items would automatically be shipped as overnight / express mail once inside Norway, and handed to the Norwegian postal system. A parcel from New York to where I lived would take 2-3 working days, and as a bonus, USPS Int'l Express only cost around $50 for the same size parcel!

So while not the same type of arbitrage as OP posted about (where items become cheaper due to free shipping), I could save a lot of time and money.

Maybe a more extreme example would be the ultra cheap shipping prices from China. You paid like $1 in shipping, which would have cost $10 if you bought the same service domestically.

IIRC, the root of these practices go back many, many decades. And has a been a thorn on the side of modern shipping ever since Chinese e-commerce exploded.

          Assuming it's the US we're talking about, the federal minimum wage is $7.25, which means that if every worker involved is paid at the minimum wage, you incur a cent of labour costs every 4.97 person-seconds. AFAICT, most Amazon workers are paid substantially higher than the federal minimum wage. And that's just labour costs.

I've used something like this list to get "over the hump" for $35 to reach free shipping without prime.

It's horribly annoying to have a product that is $34.99 and you want it, but it'll cost shipping unless you get the damn Volkswagen screw; and then Amazon ships them individually anyway.

    Just play their stupid game. My wife does this all the time, buys random items just to go past the free shipping range, then the item goes into trash (or is returned, if possible).

    Even sellers started doing this, but instead of selling random items, they sell "extra hardened packaging material" conveniently at $1, $2, $3... prices. Of course when item arrives, no extra material to be seen. When questioned, one of them said "well, the package had cardboard box - that's it, wink wink, please do not report us".

The DoorDash pizza arbitrage comparison is apt. Both cases expose the same fundamental thing: venture-subsidised pricing creates artificial market conditions that clever people will exploit.

What I find interesting is how long these windows stay open. You'd think someone at Stamps.com or UPS would notice the pricing anomaly, but large organisations are often too siloed. The team setting international rates probably doesn't talk to whoever monitors small parcel economics.

The author mentions making a few hundred dollars - but the real question is scalability. At what volume does this become attractive enough for the postal services to close the loophole? There's probably a sweet spot between "not worth their attention" and "actually profitable."

Funny seeing this. I've been working on a site to allow people to send a letter as cheaply and conveniently as possible. I actually think letters (physical) are a great way to make an impression, often times much more so than an email. Had never considered sending an actual object lol.

At current scale (which is very small), the cheapest I can get it down to without losing money is $1.55 per letter (postage, paper, print, envelope, stripe fees, misc. hosting fees, etc.). Sadly, I have no way to compete with a $0.25 lime!

It's not arbitrage until you can make money by selling something that costs you less than what you bought it for. What it is is bundled product (item + shipping) being priced lower than just one of the elements in the bundle (shipping) therefore making a case that one might as well always buy the bundle.

    I canceled prime ~8 years ago because where I am, half the stuff I wanted was considered an “add on item” that could only be shipped free if you had > $35 of other stuff, which is a complete scam because you get that without prime.

    Maybe that was just for me (in a large Canadian city at the time) or maybe they don’t do that anymore?

    I haven’t considered getting prime since, it would be a lot more interesting if it actually provided the shipping terms they advertise.

    I did this on a mass scale. There are auction items that close at 1 cent with free shipping, so I signed up for the eBay API and wrote a bot to scrape all the auctions and bid one cent on them a minute before they closed.

    99% of the packages were Chinese sellers but the packages all came from Mongolia, so there must be some sort of postal arbitrage going on there.

    • itintheory 4 days ago

      I think it depends. I bought a Dell 1700 laser printer for the low price of $0 at a second hand store about 19 years ago. They said it was failing to pull paper from the tray, and I could have it if I wanted. I fixed the rollers responsible for feeding (turned the rubber wheels inside out), and used it for another 10 years without issue. Sure, toner costs some money, but an off-brand toner cartridge is $25, rated for 3000 pages. I have also needed to replace the drum, and at one point picked up a second 1700 into which I had to put the old drum and toner after some failure or another.

      I'd estimate I've put in $200 at most, and probably put 15-20k pages through it. Still prints just fine. It doesn't have color, or networking features, but I can share it on the network from the connected computer. I'm not sure they make anything this reliable these days, but I bet there's quite a few old laser printers floating around still.

      It looks like the billing address restriction was a "thing" years ago, but is simply too impractical for modern day e-commerce. People want to do gifting, or get things delivered to temporary accomodations like vacation spots. They are relying on approaches like heuristics (sudden purchase for something expensive going to an unusual address), plus CVV verification to help ensure that the purchaser physically has the card (still allows theft, but adds a layer).

At the same time, you'd be depriving a very valuable public service of the few cents they ask to offset the cost of message delivery to anywhere in the nation. I'm sure they'd be happy to deliver something besides spam too.

        > This appears to be the cost without subsidy, with the mail service now run by a private company.

        That just means that whatever it actually costs to deliver mail to/from whatever parts of Denmark they provide service for, the people who use the service will pay that cost plus an additional cost on top of it so that the private owner (and perhaps their shareholders) can line their pockets. The nice thing about public services is that you avoid paying that extra money just so that a small number of people can personally profit from it. You can also lose a lot of transparency and control over how the service is run.

        That said, I'm a bit envious of the lack of junk mail.

      The USPS is an amazing service. Extremely dependable and affordable. They service places that no sane company ever would and they do a pretty good job.
