As of July 2015, Wal-Mart offers printable online coupons on its website, with discounted products ranging from salad dressing and paper towels to frozen pizzas and cleaning products. Additional Wal-Mart coupons can be found on large discount sites such as RetailMeNot and Coupons.com.
Promotions on websites such as RetailMeNot may expire or apply to one use only, so they may not always work. Discount sites also frequently link to any promotions that Wal-Mart is currently running, providing nothing beyond the already-existing sale. As of July 2015, these sites feature fewer coupons than Wal-Mart does. For further savings, Wal-Mart offers sales both in store and online.
