I have an awsome site to share with you! (Thanks to my new friend Ann!)
http://shortcuts.com/home

You can register your Kroger card here, then choose the coupons on the site that you want to use and when you scan your card at the register when checking out, it will automatically take the coupons off your total!! If you use paper coupons, it will just double your savings!!
They do have other participating stores too if there are any you might use.
Check it out and enjoy the savings!!
