I've been a member of this site for a while now and I'm not sure how well known it is. It's called Tablespoon.com and it's run by General Mills as far as I can tell. It has new coupons every months and also has some great recipes for you to choose from as well. I really like it. Go here and print some coupons for cereal, etc and then look at some recipes to see what you can make with the coupon savings you're going to get.
