I had to buy some books for some college classes I was taking, and I went into half price books to just see if they had what I needed. They did happen to have the books for my classes, and I ended up saving about $150 by buying my books their used, rather than at the college bookstore. The customer service person was happy to hold the books while I went home to make sure it was the right book for my class. I was a very happy customer. I recommend checking there when you are thinking of buying books, why not pay half the price?
