things in ginza are really expensive, especially in the ginza underground in quancheng square. After living in Jinan for four years, I feel that things from RT Mart are suitable for the consumption of ordinary people. Of course, there are many people in Ginza who go in for consumption, depending on their economic ability and preferences. I think there are two reasons for their high pricing: first, their location is prosperous and the rent of shopping malls is high; Second, their enterprise positioning is positioned at a higher level of consumption. I have bought things in Ginza several times, but when I think it is not suitable for my consumption level, I will not go there to buy them. Most of them are bought in RT Mart.
