A great anniversary dinner is about the night itself, not stressing over the check when the dessert menu arrives. High-end steakhouses fill up fast on prime weekend slots, so getting your table locked in at least a month ahead gives you the exact time and room you want.
A full night out with dry-aged cuts, drinks, sides, and a generous tip runs about $500. Instead of taking a hit to your checking account all at once, you can set the table early and spread payments out quietly over more than a year.
Remember that a 0% intro APR is a repayment window, not free cash. If you still carry a balance when the 15 months wrap up, the standard variable APR kicks in on whatever is left, so keep your monthly payments consistent to wipe it out on time.
