Feeding 50 people on a warm summer weekend takes real planning. The best local caterers book their calendars fast, so you need to lock down your deposit before March if you want your pick of dates.
A full setup usually runs about $1,800. If you do not want to pull that cash out of savings all at once, you can buy yourself time by spreading the bill out over a realistic timeline.
Remember, a zero-interest window is a deadline, not free money. If you still carry a balance after the 15 months are up, standard interest kicks in on whatever is left, so stick strictly to your $120.00 monthly payment plan.
