The new promotion works the same way, although it gives double the benefits to Bluebird cardholders. To take advantage of the deal, which lasts through Feb. 28 of next year, customers can either go online to the Savings Catcher website or use the Walmart app and scan their Walmart receipt. The Savings Catcher tool works as it normally does and searches for a lower advertised price offered by competitors. If it finds a better price, Bluebird cardholders can click on “Redeem to Bluebird,” which will automatically trigger a deposit of double the savings into their account.
