Gather clothes, books, sports gear, or toys that are still in good shape and invite a few households to do the same. A simple version: each item you bring lets you take one item home. Leftovers can be donated. Everyone leaves with something useful and without a receipt.
For fast-growing children, a lower price on clothes can be the right call because the fit will change. For adults, a well-made secondhand piece often outlasts a bargain that fails. The swap lets you test that without spending first.
Start this week
Fill one bag with things your household has outgrown and text one friend about a swap date.
