A good 65-inch OLED TV transforms movie nights with pure blacks and vibrant contrast, and if you buy the right one, it should easily last you a decade. You are paying for a centerpiece you will look at every single day, so the goal is to get the best hardware once instead of settling for a cheaper model you will want to replace in two years.
Timing is everything here because TV prices drop fast. New models hit stores in the spring, which means you can grab last year's proven version during Super Bowl clearances or late November sales for a fraction of the original price.
Keep in mind that the 0% intro APR for 15 months is a hard deadline, not free money, and any remaining balance left when that window ends will get hit with standard interest.
