There are lots of used paperbacks here, and if you are looking for a copy without having to pay full price, you might find it here.
The titles cover romance novels, sci-fi mostly, you will find some religious titles and a few others. There are a few hardcover titles to choose from as well.
You will not find many new releases here, however, and if you are looking for a speciality title or something veyr specific, you will not find it here.
But for sci-fi, I always manage to find a title I want and the odd book occasionally. And the prices can't be beat. They also buy used books. A nice alternative to the sometimes expensive new book stores.
