The rehearsal dinner is the last quiet moment you get before the wedding chaos begins. Since these usually happen on Friday nights, you need to lock in your spot at least six months ahead of time. Waiting too long means settling for a venue that is too far away or too expensive for what you get.
A typical small dinner runs about $2000 once you factor in the food, drinks, and tip. We can make that number feel smaller by spreading it out over a year and a half. Using a 0% intro APR for 15 months on purchases and balance transfers lets you pay for the night in monthly installments instead of one giant lump sum.
This intro window is a deadline, not a gift of free money. If you still have a balance on the card after the 15 months are up, the standard interest rate will apply to whatever is left. Make sure you have the full $2000 paid off before that window closes.
