Using coupons for Walmart is a MUST! While the brand does not have a regular weekly grocery ad, their everyday low prices can be sometimes be combined with manufacturer coupons for the best savings. Plus, Walmart allows customers to price match for select competitors AND the Walmart coupon policy allows for overages than can be applied to other products in your purchase. Don’t forget to use the Savings Catcher app: Upload pictures of your Walmart receipts; if an exact product is available at a lower price than you purchased it for, you will be credited the difference. Note: Prices at Walmart can vary by region. View the Walmart coupon policy
