Cars cost enough to keep running between fuel, routine service, and insurance. If you want to protect your cabin or refresh worn upholstery, late autumn inventory clearouts are usually when prices soften on auto accessories.
Keep your buying strategy separate from how you pay for it. Haggling over retail gear gets you the best entry price, while a 0% interest card window lets you spread out the cost of extras like custom seat covers without eating interest charges.
A 0% intro APR window is just a deadline, not free money. If you still have a balance on the Discover it® Cash Back after 15 months, regular interest rates kick in and wipe out whatever savings you got during the autumn clearout sales.
