While Bookman's trades in music, movies, software, and video games, it is best known for books. It's a great place to pick up the latest paperback, kids' books, or mystery. The selection is decent, and the prices are pretty good. Bookman's is a fun place to spend a couple of leisurely hours flipping through or reading books, magazines, etc. They also have activities for kids and adults on a regular basis.
Trading in your books is not an easy task, however, as they frequently don't seem to need what you have, unless it's the latest hot item. I recommend Bookman's, but don't get your hopes up too high about selling your stuff there for a high price.
