I have seen some great cookbooks from this site at prices that are hard not to pull out the credit card and order.

Look at the clearance center. If you cook and you like cookbooks this is the motherload of cookbooks and good prices for them. I had forgotten about it until a friend reminded me to look there for a book I gave to one of my kids, The Bread Bible.
