This week Walgreens has 8 oz. Black Forest gummy bears on sale for $1.99 w/card.
Buy one bag for $1.99 and get a Register Reward for $1.99.
Rinse and repeat (ie use coupon to buy another bag of gummies and you will get another coupon) for almost unlimited gummy bears! YMMV as this may be regional.
Edit to add: Don't use your reward points balance to pay for these or you won't get the manufacturer's coupon. Also, you need to buy these in separate transactions in order to get the coupons to print. Thanks JenT4685
