I and many others hate these people. They prey on desperate college students who are trying to sell books they don't need and then make you pay to get the book back if they reject it (and they definitely will for no reason). I haven't heard one success story and they will steal your book because you can't afford to pay them to send it back.

Yes! I sent a perfectly good conditioned book to them and now they are telling me they won't accept it. If I want my book back, I have to PayPal them $4 or else they will keep the book for themselves...

Such thieves. It was a $25 book.
