Group-bought products will definitely be lower than those in supermarkets, that is, the prices given by merchants are the lowest, and it is normal that the ex-factory price and retail price are too far apart. Product quality has little to do with this, mainly because of the reputation of the group buying network. Be sure to choose a website with a good reputation for group buying, such as Bashi Group Buying, or you can go to Fanke to buy clothes. It's all good.
