Owning a car comes with constant expenses, from fuel to routine maintenance. Small upgrades make daily driving much better, but you do not want to pay full price for them. Window tinting is one of those upgrades where timing changes the price tag. Shops get busy in the summer, but winter months bring a slump, which means better rates for you.
Always negotiate the shop price first before you think about how to pay. Once you set the job total, using a zero-interest credit card window lets you spread out the bill without adding extra costs.
Keep in mind that a 0% intro APR is a payoff deadline, not free money. If you still carry a balance when the 15 months end, regular interest applies to whatever remains.
