A good set of custom molded floor mats keeps your car's carpet clean through years of salt, mud, and spilled coffee. Keeping a car running well is already pricey enough with gas and maintenance, so you want to time your gear purchases right. Prices on weather mats tend to dip late summer before the autumn mud season hits, or right around holiday sales.
Negotiating the price with the dealer or online shop happens before we talk about how you pay. Get the price locked down first, and use a financing window only for the final total if you want to spread the cash out over a few months instead of paying it all today.
That intro window is a firm deadline, not free money. If you still have a balance left on the mats when the 15 months run out, standard interest charges will kick in on the remaining amount.
