My point is that amazon makes it difficult to see who exactly youre buying from and to know that you're getting it from that seller under many circumstances. Also, there is the first sale doctrine, so they most likely do not need to be "authorized" to sell by Rolex unless you can only purchase a rolex by signing away the roght of first sale. (I'm not sure that's possible to do and am sure it's come up with Tesla, but haven't looked for any relevant cases.) (Whether or not you trust that seller enough to give them that kind of money is a separate issue; I do not.) This isn't about these companies reselling food, its about them acting as an agent of the restaurant when they are not. They're also not selling me a "cheese pizza" for delivery and giving me one from a local place, they're selling me "company X's cheese pizza" for delivery, when Company X may not want their pizza delivered and has no knowledge of their listing by this company acting as their agent.
