Supermarket shopping cart refers to a kind of shopping equipment that we use in supermarket shopping. It is an indispensable tool in our lives. Using shopping carts when shopping in supermarkets can increase buyers' more demand on the one hand, and on the other hand It has further increased the seller's trading volume, which can be described as a win-win result with two birds with one stone. Supermarket shopping carts appeared in the American market and slowly entered our country. As we joined the WTO, a large number of domestic enterprises learned to open self-selected supermarkets in the United States, and gradually eliminated retro canteens, and also gave shopping carts the opportunity to enter the domestic market.
