Raintree has a huge warehouse of used books to explore. You can really find some goodies if you look long enough.
They also carry almost everything you could want new. If they don't have it, they will order it fast.
The staff is knowledgeable and friendly.
You can call ahead to see if they have what you want, their inventory is all computerized.
They will even maintain a list for you and call if a used copy of what you want becomes available.
They have a large section of used audio books, but they are a bit pricy in my opinion.
Trade, buy, sell.
Trade policy is 1/2 your credit, 1/2 cash for all transactions.
Large children's section also available.
