Cars cost enough just to keep on the road between gas, insurance, and routine maintenance. When it comes to comfort upgrades like window tint, timing the purchase saves real money. Tint shops see massive rushes starting in late spring, which means peak prices and packed schedules. Reaching out in late winter or early spring gets you off-season attention before the rush.
Always negotiate the job before you figure out payment. Treat the tint installation as an isolated expense, lock in the out-the-door price with the shop first, and then decide how to float the charge without cutting into your monthly cash reserves.
That 15-month intro window is a firm deadline, not free money. If you carry any balance past the end of the promotional period, standard interest rates kick in immediately on whatever remains.
