Consignment: online shop consignment, also known as online shop agent. Online shop sales are basically divided into virtual goods sales and physical goods sales. Consignment refers to some websites that provide online wholesale services or vendors that can provide wholesale sources, and reach an agreement with people who want to do online shop consignment, providing them with data such as pictures of goods, rather than physical objects, and providing them to online shop consignors for sale at the consignment price. Generally speaking, the online shop agent sells the goods pictures and other information provided by the wholesale website on his own online shop, and informs the wholesale website to deliver the goods for him after selling the goods. The goods sold are only sent from the wholesale website to the buyer of the online shop agent, and the online shop agent can't see the sold goods in this process. The after-sales service of online stores is also exercised by wholesale websites.
