A checkout offer can turn a routine purchase into a credit decision made in a few seconds. The discount is immediate and easy to see. The interest rate, fees, and conditions that apply later take more work to find. Reading the written terms before agreeing can help you understand what the offer actually requires.

Act I: The discount is only one part of the offer

Store cards, also called retail or private-label cards, are often offered at the register with a discount for opening an account. The offer may be useful to a shopper who planned to buy the item anyway, but the discount does not tell you what carrying a balance could cost. The Consumer Financial Protection Bureau (CFPB) says more than half of the 100 largest retailers offer a store card with a major issuer. In 2024, about one in four credit card accounts was a store card, with more than 160 million such accounts open, according to its review of retail credit cards.

The rate deserves particular attention. The CFPB found that many private-label cards use a fixed annual percentage rate, or APR, meaning the rate is the same for cardholders rather than varying with each person’s creditworthiness. Its 2025 report to Congress put the average APR for store cards in 2024 at 31.3%, compared with 25.2% for general-purpose credit cards. These are averages, not the terms of every card. The rate in the agreement offered to you is the relevant one to read. The CFPB’s 2025 credit card market report provides more detail on those figures.

Act II: Start with the rates-and-fees table

Look for the table of rates and fees at the beginning of the cardholder agreement. It is commonly called the Schumer box, and its standardized layout is meant to make important costs easier to compare. The table can list the purchase APR, promotional APRs, whether a rate is fixed or variable, the grace period, fees, and how interest is calculated. A guide to reading the Schumer box describes the table and its usual contents.

APR means annual percentage rate. It expresses interest and certain fees as a yearly cost relative to the amount borrowed, so it is not always the same as a simple interest rate. It also does not tell you exactly how much interest you will pay: the balance, payments, and timing matter. Read the agreement for the actual rate and the method used to calculate interest. The CFPB says the card company must disclose the APR before you agree to use the card, and its credit card key terms explain terms such as APR and fees.

Check the purchase APR even if the offer highlights a promotional rate. Note whether the regular rate is fixed or variable, and look for any annual fee, late-payment fee, cash-advance fee, balance-transfer fee, or foreign-transaction fee. A balance-transfer fee may be a percentage of the amount moved or a fixed amount, whichever is greater. The agreement also covers liability for unauthorized transactions. These details matter because a promotion may apply only to a particular purchase or for a limited time, while other terms continue to apply.

Read the promotion’s exact wording

Two offers can sound nearly identical at the register but work differently. “No interest if paid in full within 12 months” usually describes deferred interest. “0% intro APR on purchases for 12 months” describes a zero-interest promotion. Check the written offer and agreement rather than relying on a short verbal summary. The CFPB explains the distinction in its guidance on promotional financing.

With deferred interest, the promotional period postpones interest rather than removing it. If you do not pay the full qualifying balance by the deadline, interest may be charged back to the original purchase date on the balance owed during the period. Minimum payments are still due on time while the promotion is active. The CFPB also explains that being more than 60 days late on a minimum payment can cost you the deferred-interest plan. Its deferred-interest explanation lays out how that arrangement works.

A zero-interest introductory APR works differently: no interest accrues during the promotional period, even if some balance remains when it ends. After the period, the regular rate generally applies to the remaining balance. That can still be costly, but it is not the same as charging interest retroactively from the purchase date. Look for the promotion’s end date, the balance it applies to, and any language saying a late payment can end the offer early.

Ask questions before you accept

If the written terms are not available or you cannot read them before applying, pause and ask how to review them. Useful questions include whether the promotion is deferred interest or a zero-interest APR, when it ends, which purchases qualify, and what rate applies afterward. Ask whether a late payment can end the promotion or change the rate. If a rate is variable, look for how it may change.

A cashier’s pitch is not a substitute for the agreement. A discount can draw attention to the immediate saving, while the card’s costs depend on what happens after the purchase. The CFPB has reported that getting a deal on a particular purchase is a common reason people give for opening a store card. Take time to compare the purchase APR and fees with another card’s written terms, if you are considering one. The CFPB’s figures are broad market averages, not a forecast of what any particular account will cost.

Keep the terms in view after checkout

Card terms can change, so the agreement you read at opening may not remain the only notice that matters. Keep the disclosures and later account notices, and check the current terms if you use the card again or consider carrying a balance. If a point is unclear, ask the card company to explain it in writing before you agree. This article is educational, not personal financial, legal, or tax advice.
