Ordinary group buying, before group buying, most businesses have the psychological price of this group buying in their hearts. Merchants worry that if the price is too low, few people will buy it. As a result, businesses will make small profits but quick turnover, even lose money, and at most earn money at a loss. Merchants can't achieve satisfactory results. Therefore, merchants will not put the price at the lowest, and this group purchase will not last long. However, consumers only get small benefits occasionally in this kind of group purchase, and the preferential strength is not great. Mercure Group's model is to directly attack the psychological price system of merchants from a professional perspective. Merchants should set the order price for 20 people, 30 people and 100 people in advance. If the number does not exceed these people, the group purchase cannot be concluded. Such a rule allows businesses not to worry about small profits but quick turnover, and allows businesses to quote consumers the lowest price they can afford without any worries. In this way, as long as the scheduled consumers reach the required number of orders, low prices are naturally very simple.
