I've been going to the Book Rack since my family moved here seven years ago and I am rarely disappointed. The books are usually a clean half off of the cover price and pretty up to date. The owner keeps a good supply of new books and allows for trades for books or credit. There are a few locations and the owner has no problem hunting down a book for you if you need it. There seems to be a heavy emphasis on science fiction and romance novels, but he keeps a good variety over all.
