Taste of Home has reduced the price of many of their cookbooks to just $5 (regularly $24+). Here is the link to take advantage of this offer. While you're there, make sure you check out the rest of their clearance, they have some nice things marked way down!
I ordered some things from them recently and was pleased at how quickly I received my package.
Thanks, STL Mommy!
By the way, another GREAT source for cheap cookbooks is Ollie's Bargain Outlet. It is like a Big Lots, but if you have some time you can get some great things. They have a large selection of books, as well as carry a lot more items. My local store carries a ton of cookbooks, covering any type of cooking you'd want to do (or not want to do ;))
If you want less clutter, one of my favorite recipe e-mails is from Pillsbury. They even have a Cooking for Two e-mail. Of course, if you don't want the e-mails, you can always just access recipes on their site.
