Retailer Coupon Stacking Rules

Which major US retailers let you stack coupons, what each stack excludes, and how long price adjustments stay open. Every entry lists its source and the date it was last verified — policies change, so check the source before you buy.

  One manufacturer coupon per item can usually combine with a store/Circle offer — limits are set coupon by coupon in the terms.

• Amazonsecondary

  Coupons are limited to one per customer per item and promo codes don't combine — but layers stack in practice: a clipped coupon + Subscribe & Save + a Lightning Deal + card cashback can all apply to one item.

  No price adjustment

• Walmartsecondary

  The strictest of the big boxes: one coupon code per order, and its coupon-verification system can flag accounts for abuse.

• Kohl'sofficial

  Up to 4 coupons per order: one sitewide percent-off, multiple category dollar/percent-off codes, and up to 6 dollar-off rewards (Kohl's Cash / Rewards Cash) — free-shipping codes combine with anything. Application order: category codes, then dollar-off, then sitewide percent-off.

• Neweggofficial

  Promo codes are single-use and one per item, and cannot combine with combo discounts; a Combo Special bundle is one combo per order. Mail-in rebates: one per manufacturer.

• B&H Photosecondary

  B&H sells under MAP (minimum advertised price) agreements, so public stacking of multiple coupons isn't offered — promotions are item-specific.

  One coupon per order; store managers occasionally make exceptions in person, but nothing is systematically published.
