If you are planning to order groceries for pickup from the Walmart Grocery app or website, take advantage of this valid promo code I found for $10 off $50 minimum order! I just used it myself, so I know it works. Just enter it in the promo code box at checkout.
PROMO CODE: LA9ARAAC
I do not know the expiration date, but it definitely works as of today, so don’t delay if you plan to use it! It could end at any time.
