Thanks to Angela at WVTreasures, I've found a wonderful website called The Best Amish Cookbooks that sells just that...the best Amish cookbooks! :) To me, their prices seem very reasonable.
Besides cookbooks, they also sell Amish dolls, Amish books, cookies, and jams/jellies. They have a monthly contest where you can win a different prize each month. This month's prize is a cookbook sampler called Homemade Cereals. It contains 70 different recipes that include granolas, grapenuts and cooked cereals. You can find their Monthly Contest HERE.
Just thought I'd pass along this website in case Amish cookbooks are at the top of your list, too. :)
