I've actually had only two problems with ordering anime from the Amazon Marketplace. One sent me the Fushigi Yugi OVA set when I had ordered the first box set, which I was able to exchange for it without an issue. The time where I was trying to find the second box set to the series was when I got a Chinese bootleg copy that I didn't like. I sent it back, but I don't think I ever got my money back, mainly because it was sent in so many weeks after I realized it was bootleg. Still, most of the other times were fine.
