Picture a hot Saturday in mid-July with half the block parked in folding chairs and kids running through sprinklers with melting waffle cones. A great neighborhood gathering comes down to timing. Local scoop shops and mobile carts book their summer weekends months ahead, so waiting until June usually leaves you buying standard grocery tubs at the last minute.
Covering the catering, toppings, and paper goods runs about $600. If you do not want to chase down neighbors for small payment transfers upfront or wipe out your summer cash in one shot, you can stretch that cost across a zero-interest window and pay it off quietly over time.
Keep in mind that an 18-month zero-interest window is an extended deadline, not free money. If you still carry a balance when those 18 months wrap up, the card's regular ongoing interest rate applies to whatever is left over, so set up an automatic payment for that $33.33 each month and finish on schedule.
