Do you have any good suggestions for opening a supermarket near your home?

It is recommended to open a supermarket chain, and don't be cheated everywhere. My relatives opened a supermarket chain in their town, called Joe's supermarket chain, and the business was very good. The main reason is that he took cheap things and charged 100 for 30, all of which are big brands. I don't know how the manufacturers make money. Anyway, my relatives made money. Hold your head high every day.
