I was looking on Amazon today and saw that Thomas Keller's "The French Laundry" cookbook is only $17.10. The cheapest I've ever seen it before this was $30. It's a large, really beautiful cookbook (almost like a coffee table book) and would be good for advanced foodies. I say that only because a lot of the recipes are pretty intricate.
