Hosting a bridal shower doesn't mean you have to deal with a massive bill hitting your bank account all at once. Saturday mornings are the smart play for your budget because brunch food is cheaper and you aren't competing with prime Saturday night catering slots. You'll want to book your food about eight weeks out to keep the stress low.
Using the right tool for these purchases lets you spread the cost over a year and a quarter. If you put the $900 total on a Discover it® Cash Back, you can use the 0% intro APR for 15 months on purchases and balance transfers. This turns the event into a steady $60 monthly expense while you focus on the guest list.
This 15-month window is a deadline, not free money. If you still have a balance on the card when the intro period ends, the standard interest rate will apply to whatever amount is left.
