This site has to be fraud! They never paid me for one of my books which they were supposed to pay me big bucks for it. I sent them 2 books one that they paid me $7 dollars for they paid me, but the other they said they had to send it to the publisher to verify authenticity. I bought this book from my college store! Never heard from them again. I sent emails they do not respond and the book disappeared. I called they said that there was a problem with their system and they were let processing the payments and asked me to put this review online that would make them go faster
