This story comes to my mind. A pizzeria owner made money buying his own $24 pizzas from DoorDash for $16 https://www.theverge.com/2020/5/18/21262316/doordash-pizza-p...

#112Has this person tried it? Doesn't Amazon shipping have to go to the billing address on the credit card? Being able to purchase on a credit card and have it sent anywhere makes it that much easier to use stolen credit cards.

I don't think Amazon is losing money. It's really just that efficient. E.g. an Amazon van rolls through my street multiple times a day. What is the marginal cost of them stopping at my house and dropping off a potato?
At your house it might be fractions of a cent. At my house, it's a 140 mile round trip between the fulfillment center ("are you feeling fulfilled yet?") and the drop off location. OTOH, there's likely more of "you" than there are of "me" ...
While Amazon is efficient, "fractions of a cent" is probably the wrong order of magnitude for even the most efficient order.

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.
> then let them operate in a free market. I think you meant to say "operate in a market that is regulated in precisely the way they want it to be".
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.

#115A couple of these are still valid with Prime, but most of them are Amazon Fresh items ($9.95 service fee for orders under $50), or out of stock, or the price is now way more.

#117Ah, luckily the climate doesn't mind that oil was extracted, a phone case was produced out of it, shipped from China, to end up not even being used but just as a "greeting card". Why yes, I am fun at parties.
The oil used for shipping from Shenzhen to Long Beach is completely trivial compared to what the truck used getting it from Long Beach to Pasadena.

#119Here in Ireland, a stamp is 1.85eur. So. Many. Possibilities.
Wow didn't realize its much more expensive in some places outside the US. I'd think the smaller land area would make it cheaper.
This appears to be the cost without subsidy, with the mail service now run by a private company.
It's fine. I receive less than the average 10 letters per year (including junk mail). I check the mail box every two weeks or so.
