This bookstore specializes in used paperback books. They also sell new books and some hardcovers. Used paperbacks are either sold at half the list price or $1.75 with trade-in credits. Anyone can open a trade-in account, where you bring in used paperbacks (hardcover generally not accepted), credit is added to the account, and purchase books using that credit, paying the discounted price. Wonderful store. You never know what treasures you may find.
