Graduation season fills up fast, and the best local taco trucks get booked months before the caps and gowns even arrive. If you are planning a celebration, nailing down the food early is the main lever you have to keep stress low and dates open. Waiting until spring usually means settling for leftovers or paying rush rates.
We are looking at about $1200 for a solid truck rental that feeds a crowd. Since you are booking three months ahead of the rush, you have a solid runway to handle the cost without scrambling right when party prep peaks.
Remember that zero percent is a deadline, not free money. If you still carry a balance when the 18 months are up, regular interest kicks in on what is left.
