What "stacking" means: the layers of a discount stack
Sale prices, coupon codes, store rewards, card-linked offers, and cashback portals — what each layer is and how they combine.
Layer discounts · Pay less
Pay less by combining discounts.
Most shoppers use one discount at a time: the sale price, or a coupon, or cashback. But discounts aren't mutually exclusive. With a little planning, you can layer them — sale price plus a coupon plus store rewards plus a cashback portal — so each one applies to what's left after the last. These guides explain how the layers work, what order to use them in, and the mistakes that can silently void the whole stack.
