Stack cashback with card offers: check each layer
A portal rebate and a card-linked offer can involve different requirements. Treat each as a separate qualification check before assuming they combine.
Identify the layers
Record the shopping portal, the card’s normal rewards, and any activated card-linked promotion. Separate those from a store coupon or a welcome bonus. Each layer may have a different merchant, spend threshold, or redemption rule.
Read compatibility terms
A card promotion may specify an exact website, currency, charge amount, or merchant channel. A portal may exclude some coupons or payment routes. Check both sets of conditions before counting a combined reward.
Avoid counting the same action twice
Two shopping portals generally cannot both be credited for the same attributed purchase. Finance signup promotions may also prohibit combining benefits. Make a written plan for the layers you have confirmed, then keep the relevant receipts and activation records.
Illustration: an eligible $100 purchase with 5% portal cashback and a compatible $10 card offer could produce $15 of savings. That result is conditional on both promotions accepting the transaction.
