interesting idea to build a great community like this, of course all Steem users can get many benefits from this program. However, several important things need to be paid attention to, if a business offers services it may be easy to carry out transactions, but if the business offers goods, of course it can only be reached by the people closest to the seller. but we all hope that in the future this steem store will be able to collaborate with international couriers and accommodate a security system so that sellers and buyers are not harmed.
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.
