Coupon stacking
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.
- Cashback apps stack
- Loyalty pricing stack
- Up to 1 coupon code per order
Policy as of 2026-10-16.
What coupons don't apply to
- Subscribe & Save combined with coupons is restricted
Price adjustment
Amazon does not offer post-purchase price adjustment on general merchandise.
No price adjustment.
As of 2026-10-16.
Stack it yourself
Amazon allows 2 stacking channels — check each applies to your item, then multiply.
Discounts multiply, not add: 20% + 20% is 36% off, not 40%.
