One of the best ways to stay up to date on Walmart's sales and receive promo codes to use at Walmart is to sign up for the retailer’s email list. It’s a great way to get savings information delivered right to your inbox.
You’ll also want to use the Walmart app. Not only does it make shopping easier, but it offers touch-free payment with Walmart Pay and allows you to quickly find items and Rollbacks to help you save big.
