A milestone birthday in the backyard is memorable, but tent and seating rentals can hit your bank account all at once. If you want the setup to look perfect, you need to book your vendors at least two months before a summer weekend to avoid the rush.
You can manage this $1100 expense by planning your cash flow ahead of the event date. Staying ahead of the timeline is the only way to avoid last-minute price hikes or losing your preferred vendor.
The 18-month window is a tool for spreading costs, not a free pass. If you do not pay off the full $1100 before the time is up, you will be charged interest on the remaining balance at the card's standard rate.
