Graduation season gets busy fast, and the best artists book up months in advance. Securing your entertainment early lets you focus on the ceremony rather than scrambling for vendors at the last minute.
A professional caricature artist usually runs about $350. By planning for this cost now, you avoid a surprise hit to your bank account when the party invoice arrives.
The 0% intro window is a deadline, not a gift. If you haven't paid off the $350 by the end of the 18 months, the bank will charge you interest on the remaining balance at their standard rate.
