How they do it: Walmart’s Savings Catcher is a customer loyalty initiative which promises customers that they will always get the lowerst prices at the company’s stores. If a customer finds the same product at another location for a lower price, Walmart will credit the difference directly to a special gift card to be redeemed at Walmart.
