The difference between chain supermarkets and small supermarkets (small shops)

Chain supermarkets all purchase goods from the head office, and the prices are uniformly stipulated, but it is more worry-free to open such a chain store. When the time comes, what kind of goods will you send to you from the head office? You have to pay the joining fee every year. There are no sales restrictions.

Small stores are different. You don't have to pay the joining fee, and the price can be set by yourself. It's more troublesome to purchase goods or something.
