The campus bookstore is the biggest rip off on this campus. There are rep's for a company called Belltower Books walking around, and the one rep offered me $1 for a book the bookstore is offering $10 for, so I am skipping that route. Last semester I sold all my books back on Amazon and had no problems, and I like that I can set my own price based on the condition of the book. I bought this book on amazon from a private seller who listed it in "like-new" condition and the spine isn't even fully cracked open because i never once used this book for class this semester. I will probably end up selling it. Thanks everyone!!
