Reuse, reuse, reuse: that's the name of the game today. You love garage sales (and you're planning a mission to beat all missions), but remember, don't be gauche. Never arrive early and hassle the home's occupants. Respect their space: walking on grass, trudging through flowerbeds and blocking the driveway are unclassy moves. And always carry small bills and change to give your bargaining power an edge.
