Feeding forty people brisket and sides usually runs around $950. The real trick to keeping that number under control isn't skimping on portions; it's the timeline. If you lock in your caterer four weeks out, you avoid last-minute rush fees and get your pick of drop-off delivery slots.
Once the date is set, you can figure out how to handle the bill without taking a hit to your monthly bank account all at once.
An intro window is a repayment timeline, not free money. If you still have a balance on the card after the 18 months are up, regular interest kicks in on whatever is left, making your barbecue a lot more expensive.
