Cars cost enough to run between insurance, gas, and routine maintenance. When cold weather approaches, keeping your vehicle safe from snow and ice means grabbing winter storage gear before the first freeze, right when prices are softest in late summer.
You can rarely negotiate down retail accessories, but you can control how you pay for them. Charging a $220 custom cover to a card with an intro window lets you break up the cost without paying interest, keeping cash in your account while your paint stays clean.
An intro window is a fixed deadline, not free money. If you carry a balance past 15 months, regular interest rates kick in on whatever amount is left.
