My best/worse "duplicates" have arisen since they started using their own last-mile shipping: A package gets marked undeliverable. I go ahead and re-order the item. The next day the package is marked delivered on-time (it definitely didn't arrive the day before), and is un-undeliverable. I now have to cancel the replacement I ordered, and have to talk to customer support to make them eat the cost of it, because fuck them. There's no record on the amazon page that it was ever marked undeliverable at all - I now have started taking screenshots. I'm assuming this is some fuckery played by people in the field having trouble hitting their metrics, but I don't actually know. I just know that at least once this has ended with a next-day-shipping replacement arriving alongside the "undeliverable" item, and Amazon demanding I mail it back to get my refund. Because nothing says "fun" like now having to take the time out of my day to ship an item back to them so as not to get double-charged due to their own fucked up shipping practices.
