HauteLook is having some Random House cookbook deals today. A few of them are cheaper than Amazon, but I'm not sure about shipping prices. They have what appears to be all the Ina Garten books and the Julia Child Mastering the Art of French Cooking box set too!
Anyway, if you want to have a look - THIS is the site. You do have to sign up, but there is no charge. The link posted is not an affiliate link. I have ordered from this site though and they are reputable.
