There are two DIFFERENT types of coupons. Manufacturer Coupons and Store Coupons. Manufacturer Coupons are basically that: sponsored by the manufacturer brand named on the coupon. Store Coupons are issued by the store and are ONLY good at that store. For example an A&P coupon is good only at the A&P. A Walgreen’s coupon is good only at Walgreen’s and so on. Store Coupons will NOT double or triple. Manufacturer Coupons are good ANYWHERE that coupons are accepted. Manufacturer Coupons can be doubled and tripled unless they specify otherwise. You can use a Store Coupon, at the designated store in addition to a Manufacturer’s Coupon at that designated store for more value. As always, be aware of coupon expiration dates.
