PROS:
1) I saw a gorgeous selection of classics like Adventures of Tom Sawyer, The Black Stallion, 20,000 Leagues under the Sea. Leather bound, gold leaf pages. I salivated just looking at them.
2) If you're a fan of home schooling, this would be the place to pick up cheap reading material.
3) During Christmas you could find some a gem of a gift idea, esp. near the front of the store.
CONS:
1) They offer a dismal cash trade.
2) If you're a published author and are trying to get rid of some stock, you're lucky if they offer 50 cents and take just one book. They used to take up to 8 copies off my hands for $1 each.
