Throwing a great graduation party comes down to food people actually want to eat, and a taco truck is an easy crowd-pleaser. The catch is timing. Popular trucks book out at least three months ahead for weekend dates, so you need to lock in your vendor long before school lets out.
A typical setup runs about $1500 for a decent crowd. If you start planning now, you do not have to pay for it all in one lump sum before the guest of honor even walks across the stage.
Remember that a 0% intro APR is a window to pay off a purchase, not free money. If you still carry a balance after 15 months, high interest rates kick in on whatever is left over. Set up automatic payments for $100.00 a month to clear the bill well before the promo ends.
