I love the idea behind this - you buy books for less than what the university bookstores sell them for and sell them back for more! It's a win, win situation! The only downfall is they don't have a huge selection and so if you're taking a specialized class or a graduate class, you may not be able to find what you need. I'm guessing this is because their inventory mainly consists of books that have been sold back. If you're taking an entry level course, though, it's a great place to check out!
