Group purchase 3.0 refers to a group purchase mode oriented to users' needs. Compared with the business-oriented group buying 2.0 model represented by Groupon, an American group buying website, the characteristics of group buying 3.0 are to meet users' needs, make phone calls for users, make phone calls for gathering, and find business opportunities for businesses. Its representative websites include "Love Calls for Group Buying Network" and Group Buying Navigation Network. The concept of group call is different from the existing domestic group-buying websites such as Meituan.com, but is dominated by the "incoming call" of consumers and referred to the "incoming call" of other consumers. Finally, the website cooperates with the merchants to "respond to the call" and complete the group purchase process.

Any user who wants to buy any product can make a phone call through the group purchase 3.0 platform. The form of calling is very free, which can be a specific commodity, a commodity, a service and so on.

When a call is released, it will spread through various channels. For example, using the intelligent integration function of the group purchase 3.0 platform, the incoming call is pushed to the user who has posted the related incoming call. Incoming calls can also spread in the publisher's circle of friends through social networks (SNS). When other users receive a call, they can choose to make the same call, and the call information will be gathered on the group purchase 3.0 platform.

* * Businessmen or heads of delegations found business opportunities and started a group * *

Merchants or heads of delegations can pay attention to the information in the Group Buying 3.0 platform, such as the number of callers. When it is found that the call volume of a commodity reaches a certain scale, the merchant can initiate a group purchase. For the head of the delegation, the useful information in the platform can be used as the basis for negotiations with merchants to obtain good discounts.
