Wow! What a great widget!! Crystal and some friends over at Money Saving Mom are offering this free for a level 1 subscription. I've installed mine at the bottom of my blog. Try it. Just type in a item you need to get the next time you go to the grocery store and see if any coupon links come up.
I tried Yoplait, because that is Mr. Wonderful's favorite type of yogurt. There was several coupons to pick from.
