Wedding vendors book up fast, especially the unique ones like converted horse trailers. You want the memory of your friends piling into a vintage booth, but you probably don't want to drop $1,400 during the busiest month of your life. It's better to plan this around the vendor's slow season.
The move is to lock in your date during winter wedding expos when companies offer package credits. By using a specific timeline, we can break that big cost into small pieces. You get the booth you want without the immediate hit to your savings.
The 0% interest period is a temporary window, not a permanent discount. If you still have a balance on the card after the 18 months are up, you'll start paying interest on the remaining amount at a much higher rate.
