1, the price is limited: Vipshop is a special sales model in the shopping party, which is sold by means of limited time snapping and group buying. There are certain discounts and concessions on commodity prices, which are agreed with suppliers or partners in advance, or decided by Vipshop according to market factors. Shopping parties can't compare prices because Vipshop has restrictions on price disclosure or its factors.

2. Protect the interests of partners: Vipshop has a specific cooperative relationship with some brand partners of the Shopping Party. In order to protect the interests of partners, limiting the price comparison function can prevent consumers from finding the same product with lower price through price comparison, which will lead to the sales damage of brand partners.
