Introducing Cellfire

Cellfire is a web site that will transfer coupons and savings to your grocery store cards. From what I can tell they are hooked up with discounts and coupons for Vons, Pavillions and Ralphs. You can register by giving them your email address, birth year, phone number and your store card number. Then you browse through the products on which they have savings in each store. For example they've got "Save .75 on Betty Crocker Supreme Brownie." You click the "Save to Card" link under that product and it sends that savings directly to your card. So you can go to the store, buy the brownies, show them your card and you'll get the 75 cent discount without a coupon. Seems pretty clever, right. I've signed up for it but don't know if it works. If anyone has tried this, let me know.
