Social shopping allows potential buyers to obtain information and opinions issued by other buyers with similar profiles, on products and services they are planning to acquire. On another hand, under companies’ point of view, social shopping offers them a way to analyze the market and detect consumers’ tendencies. In the present article we propose a model that expands the models of current social shopping by adding the possibility of the community to procede to self determination of the products and services basket, by determining what they want to buy, and in some occasions, when. This way, instead of allowing a brand or product to create in the community users the need or will to buy, it is the community itself, through social networks, to self-influence in the sense of defining what are the products and services they want to be marketed and in what way, thus obtaining better prices and reaffirming its identity.
