I'm not sure I blame them. Amazon once used USPS to send me half a dozen office chairs. I called Amazon as soon as I saw the shipping update and said there's zero chance whatsoever they will ever reach my door. Nothing they could do. I just ordered from another vendor the same day and waited the inevitable 2-3 weeks for the Amazon order to work its way through the system and back to Amazon without delivery ever attempted.
It's one of a few things that perplex me about Amazon. Like why can't I just flag a shipping method as unusable. Why can't I search for stuff only sold by Amazon. Why can't you fucking stop selling fake chargers and headphones?
But what do I know about running a multi billion dollar business right?
