You finally got the keys, and now you want to feed everyone who helped you move boxes. A casual gathering like a big taco bar usually runs about $650 once you stock up on meats, tortillas, and all the fixings.
Because these are deadline purchases, lead-time is your real lever for keeping costs down. Buying proteins and pantry staples in bulk two weeks ahead lets you shop sales and prep without last-minute panic buying at marked-up prices.
Remember that the 18 months on purchases is a deadline, not free money. If you still have a remaining balance when that window ends, standard interest kicks in fast on whatever you have left.
