Pay the full statement balance by the due date on a card with a grace period to keep back-to-school purchases interest-free. Use the store discount at checkout, then clear that purchase before the grace period ends. A store credit card is a retail card tied to one chain or group of stores. A grace period is the interest-free window between the purchase and the due date when you start with no balance.

How does the grace period keep purchases interest-free?
The Consumer Financial Protection Bureau explains in its grace-period guidance that carrying no balance and paying the full statement balance by the due date avoids interest on new purchases. That rule applies when the card offers a grace period. It covers eligible new back-to-school purchases added during that billing cycle.
Start the school season with a zero balance when possible. Charge only what you can repay from the next paycheck. Pay the full statement amount, not the minimum, by the due date.
Why is deferred interest different from 0% APR?
Deferred-interest promotions promise no interest only if you pay the full promotional balance by the deadline. The Consumer Financial Protection Bureau notes in its explanation of promotional financing that this differs from true 0% APR, where no interest accrues during the promotion. With deferred interest, leftover balances can trigger retroactive interest.
Best Buy says in its financing terms that paying the full purchase before the promotional term ends avoids interest. Any remaining balance triggers interest charged from the purchase date. A laptop left partly unpaid can therefore cost far more than expected.
What does Target's 5% discount actually cover?
Target states in its Circle Card rules that Target Circle Cards take 5% off eligible purchases at Target stores and Target.com. The discount applies after other discounts and only to the amount charged to the card. A $80 backpack order reduced to $70 by store sales earns 5% off $70 paid with the card.
The same Target rules exclude prescriptions behind the pharmacy counter, gift and prepaid cards, prior purchases, and memberships. They also exclude taxes, shipping, delivery, and other fees. Buy school supplies and eligible clothes with the card, but expect no 5% cut on excluded items.
How do you keep the saving interest-free?
The Consumer Financial Protection Bureau warns that retail store cards may carry higher rates than general-purpose cards. The Federal Reserve reports average card APRs above 22% for accounts assessed interest in 2026. Revolving even a small school-supply balance can erase a 5% checkout saving within one or two months.
Charge a set list of supplies you already budgeted. Keep the receipt total below what your checking account can cover. Pay the full statement balance by the due date, and do not carry the balance for financing.
