How store categories affect your credit card rewards (2026)
Every store is classified by card networks into a spending category that issuers use to apply — or deny — category bonuses. Costco (wholesale), Walmart (discount store), and Starbucks (restaurant) all behave differently than shoppers expect.

Why most people pick the wrong card
Consumers buy groceries at Walmart and expect grocery bonuses — but the discount-store category blocks the bonus.
How Pikt routes smarter than guesswork
Pikt links the cards you already carry, weighs your offers and category earn rates, and tells you the best card to use — with a plain-English explanation and dollar estimate for every purchase. Pikt Checkout names your best card before you click pay. You still pay with your own card. Coming next: Pikt Nearby will name your best card on your lock screen when you're ready to pay in stores. Pikt uses merchant-level data, not store branding, to route your purchase.
Frequently asked questions
- Can I look up how a store is categorized?
