Wal-Mart accepts the widest variety of coupon types, says Bowsher. Wal-Mart now accepts manufacturer coupons, which you can stack with store coupons or sale items, says Woroch. The store doesn’t limit the number of coupons you can use per visit either, although you can only use one coupon per item.
Wal-Mart also offers the Wal-Mart Discover card, which earns 1 percent back on all purchases, plus 5 cents off each gallon of gas at Wal-Mart gas stations, says Novickis.
Wal-Mart also promises to match competitor prices, so if you happen to find a product for less elsewhere, present the price to the manager to get a match.
