I have seen a great many complaints about that site, but the thing that made me 100% certain that vendor is not just a bad seller but an actual con artist out to steal your money was their "policies" page. This is something I have a bit of experience with. Someone went to a lawyer and asked for a disclaimer that allowed them to screw people intentionally here. No such thing, really, but that was the intention in writing this. This guy is a bad egg.
