Picture your housewarming party packed with friends, nobody stuck playing bartender in the kitchen, and a custom signature drink waiting on the counter. Booking bar staff and cocktail service on a Friday evening instead of a peak Saturday is the easiest way to save hundreds while still getting the exact vibe you want. You get the same professional service for about $700 total, but with a lot less competition for prime dates.
When you are planning a party with a hard date, lead-time is your biggest lever. You have to book the staff early to lock in the Friday rate, but you can wait on things like liquor store runs and fresh garnishes until the week of. Breaking that $700 cost into manageable pieces helps keep your cash flow steady while you get your new place set up.
Just remember that the 0% intro APR is a deadline, not free money. If you still have a balance left on that $700 when the 15 months run out, standard interest charges will kick in on whatever is left.
