A baby shower comes with a hard deadline. Once invitations go out, your date is locked, and booking a private room alongside bespoke floral arrangements can easily run around $2,200. The key is working the calendar so you aren't paying rush fees or settling for leftover options.
Securing your space three months ahead gives you breathing room to price floral vendors and line up payments without draining your monthly checking account all at once.
Remember that a 0% intro APR window is a firm deadline, not free money. If you still have a balance when the 18 months wrap up, regular interest applies to whatever remains, so stick to the monthly target until it is fully cleared.
