They give you 75% off of the book price if you bring a book to trade...and they accept every paperback you bring even if they have overstocks. Every book is shelved (not just the high-priced ones) so you can find tons of books for 25 cents. It's the best deal in Austin. The Sci-Fi and Romance sections are huge.
Pros: Cheap, Knowledgable staff
Cons: Needs paint
