A consignment shop transaction is a type of resale, which involves the sale of goods from one party to another. The goods are usually owned by the seller, but are stored and sold in the consignment shop. The shop owner takes a commission from the sale, and the seller receives the remaining amount. This type of transaction is beneficial for both parties, as it allows the seller to make money from items they no longer need, while the shop owner can make a profit from the sale.
