The cashier offers 20 percent off if you open a store card on the spot. Financial planners say pause before you say yes.
The Discount Math
Twenty percent off sounds generous, but store cards average around 30 percent APR versus about 21 for a typical card. If that holiday balance lingers, interest swallows the discount whole. The National Foundation for Credit Counseling says never decide at the counter — ask for the terms in writing.
The Deferred-Interest Trap
Many store cards advertise 0 percent for 12 months, but the fine print often says deferred interest. Miss the payoff window and you owe retroactive interest on the entire original purchase. Clark Howard calls it hideous retroactive interest; the CFPB warns the same.
The Hard Inquiry
Opening any card triggers a hard pull on your credit report, and several in one season can ding your score. Planners say one thoughtful application beats three impulse sign-ups.
When It Can Work
The offer works when the purchase was already planned, you pay in full that month, and the card won’t spark extra trips. The NFCC’s rule: only charge what you can clear in one billing cycle.
