Here’s what consumers have asked with answers from sellbackyourBook.com staff and previous consumers.
I just received a book from them that was a total piece of $#*!. Don't buy from them.
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.
