It's like a bulletin board, all forms of information related to the announcement (promotion of goods) can be directly confirmed in the user comments field. Transactions are made based on their trust in those goods and services, the closest scope may be better. What is clear is that this has nothing to do with buying and selling application programs, only the simplest means of promotion in the form of a community that focuses on buying and selling information on goods and services.

Thank you for your greetings and comments friend.
