Using Coupon Codes on Previous Purchases

Walmart does not allow the use of coupon codes on previous purchases. Coupon codes are typically applied at the time of purchase and cannot be retroactively applied to completed transactions. If a coupon code is not used during checkout, it cannot be applied later.

Coupon Policy

• Walmart accepts manufacturer coupons and some digital coupons through their app, but these must be applied at the time of purchase.
• Coupon codes from third-party sites can be used during checkout for online orders, but they must be valid and applied before completing the purchase.
• There is no provision for applying coupon codes to previous purchases.
