“Consignment shop” is an American term for second-hand stores. However, for special second-hand shops that sell used goods for owners (consignors), typically at a lower cost than new. Not all second-hand stores are consignment shops. In consignment shops, it is usually understood that the consignee (the seller) pays the consignor (the person who owns the item) a portion of the proceeds from the sale.
Payment is not made until and unless the item sells. The consignor retains title to the item and can end the arrangement at any time by requesting its return. A specified time is commonly arranged after which, if the item does not sell, the owner can reclaim it (or if not reclaimed within a period, the seller can. Consignment shops differ from charity or thrift shops, in which the original owners surrender physical possession and legal title to the item as a charitable donation, and the seller retains all proceeds from the sale.
