The pitch comes at the register, when you are holding a full cart and a total you would rather not look at: open a store card today and take a percentage off this purchase. It is a well-timed offer, and it is not always a bad one. But the card behind it is a real credit card with some of the highest interest rates in consumer lending, and the decision deserves more than the fifteen seconds the cashier gives you. Here are the pros, the cons, and the rule for deciding on the spot.

What a store card actually is

Most store cards are private-label cards: issued by a bank on the retailer’s behalf, usable only at that store or its family of brands, and often paired with a co-branded version that works anywhere. They are easier to get than general-purpose cards, which is why they are pitched so freely. They also cost more to carry. In its 2025 market report, the CFPB put the 2024 average APR on private-label store cards at 31.3%, against 25.2% for general-purpose cards, the highest figures in its series going back to 2015. A separate CFPB spotlight in late 2024 found the average retail-card APR had reached 32.66%. The same market report found that one in five private-label accounts made only the minimum payment, which is the customer the discount is designed to attract.

The pros

  • The sign-up discount. A percentage off a large purchase is real money if you would have bought the item anyway and you pay the statement in full. On a big-ticket purchase the one-time discount can exceed what a 2% flat-rate cash-back card would have returned.
  • Ongoing perks. Cardholder-only sales, free shipping, extended return windows, and rewards that pay out in store credit. Worth something if you shop there regularly; worth nothing if you do not.
  • Easier approval. If your credit is thin or bruised, a store card may be approved where a bank card is not, and it reports to the bureaus like any other revolving account. That makes it a legitimate credit-building tool, provided the balance is paid in full.

The cons

  • The APR. Above 30% on average, a store card is one of the worst places to carry a balance. The sign-up discount is one-time; the interest is monthly and continues until the balance is gone, so a discount on today’s purchase is quickly consumed by a few months of interest on the same purchase.
  • Deferred interest. Many store financing offers are “no interest if paid in full in 6 or 12 months.” That is deferred interest, not 0% interest: interest accrues from the purchase date at the card’s regular rate, and if any balance remains when the promotion ends, all of it is charged. The CFPB’s example is a $400 TV on a 6-month offer with a small balance left at the end; the back interest comes to about $65. About one in five deferred-interest balances ends up charged that retroactive interest, and roughly $70 billion of purchases were financed this way in 2024. Most of that volume sits on 6- and 12-month terms, which are also the easiest to miss.
  • The hard inquiry. A card application triggers a hard pull, which typically costs fewer than five points, stays on your report for two years and counts toward your FICO score for 12 months. Card applications are never grouped by the scoring models the way mortgage or auto inquiries are, so a store card opened while you are shopping for a mortgage is a small, avoidable dent at the worst time.
  • Utilization on a small line. Store cards often come with low limits. A modest purchase on a low limit reads as high utilization, and the standard guidance is to keep every card under 30% of its limit. If the store card is your only card, the effect is magnified.
  • Closing it later hurts, too. The account stays on your report for up to ten years after you close it in good standing, but its limit leaves your available credit immediately, which pushes utilization up on everything else. So a card opened for a one-time discount tends to become a card you keep for years.
  • More temptation. Cardholders get the sales emails, the exclusive previews and the reminders. If you know you spend more when you are marketed to, that is the whole cost of the card.

The rule for deciding at the register

Say yes only if all of the following are true: you would have bought the item anyway, you will pay the statement in full, you shop at that store often enough to use the perks, and you are not planning a mortgage or auto loan in the next year. If any one of those is false, the answer is no, and the discount is not big enough to change it. If you are offered deferred-interest financing on a large purchase, take it only with a payoff plan that clears the balance a month early, and keep that purchase on its own card so it is not mixed with ordinary spending.

If you already have a store card, use it for the perks, pay it in full, and keep it open with an occasional small charge rather than closing it. What closing does to your score, and the downgrade alternative, is in how to cancel a credit card the right way. And if the reason you are considering a store card is that you are carrying balances elsewhere, the more important read is the 2026 credit card APR escape plan.
