As a former English major, this little shop is like heaven to me. HEAVEN! I traded in about 15 books and donated 2. In total, I earned $30 credit which means that they take 1/2 off your purchases until you reach the total credit amount you have earned (this is kept on file for you in case you don't spend it all at one time). My only suggestion to people who plan to shop here is to bring a list of books you are looking to find! I was so overwhelmed by the amazing selection that I could not remember what I wanted to read and could have walked around for 2 hours if I did not have other people with me!
