As near as I can work out, their business model is now based on your being able to send back completely wrong or broken things they've sent you, so I stick to stuff where I've got the luxury of going through a cumbersome return process if things go terribly wrong.

My address has also been used as a target for a scam where, by sending unwanted goods to a real customer, a seller can fabricate a fake review that counts in their system as real. In one case it was a garbage light (shipped directly in its retail packaging so I could see what the thing was) that by a strange coincidence was the top-rated light on Amazon. Clearly an exploit that pays off.

I stopped (I think) that behavior by returning some unsolicited packages to sender, at the post office.

I'm pretty much down to a few books, video games, and obscure fasteners/hardware/tools (which annoyingly they're just about the only good source for).
