For buyers, park once and walk the block: you cover more sales in an hour than driving house to house. Bring small bills and a wagon if you expect furniture or bulky finds.
For sellers, split the cost of signs, flyers and online ads with neighbours and list one shared date and map. A block sale is one street; a community sale spreads across a whole neighbourhood or town, and a multi-family sale is several households at one address.
Every block sale posted nearby is on one map, sorted by distance, with dates, hours and photos. Hosting one yourself? Posting is free and takes about two minutes.
