Picture the backyard full of family, folding tables loaded high, and that first deep smell of smoked brisket drifting across the grass. Big family milestones take real planning, and the smartest move you can make is locking in your dates before the rush hits.
If you aim for off-peak months like September instead of mid-summer, caterers often have better availability and more room to negotiate. A catered barbecue brisket feast for a family reunion runs about $2100, which means lead-time is your best tool to keep the math from stinging.
Remember that the 0% intro APR for 15 months on purchases and balance transfers is a strict deadline, not free money. If you still carry a balance when those 15 months end, standard interest kicks in on the remaining amount.
