There are many places where supermarkets purchase goods, including suppliers, wholesale markets and manufacturers.

There are three main sources of purchase channels in supermarkets. First of all, supermarkets will establish cooperative relations with various suppliers and purchase goods directly from suppliers. These suppliers may be professional companies in the fields of food, daily necessities and household appliances. Secondly, supermarkets will also go to the wholesale market to purchase goods. The wholesale market is a place where all kinds of goods are sold centrally, and supermarkets can choose goods from multiple suppliers to purchase. Finally, some supermarkets will directly cooperate with manufacturers and purchase goods directly from them. This way can reduce intermediate links, reduce costs and ensure the quality and freshness of goods.
