Best for: Big one-off purchases and spending outside Costco
Check annual fees and whether the rate is capped.
Grocery-rewards Mastercard
Best for: Households whose Costco run is mostly groceries
Costco is usually coded as a warehouse, not a grocery store, so bonus rates may not apply.
Travel-points Mastercard
Best for: Members who book Costco Travel or fly often
Points value depends on how you redeem; compare in cents per point.
