Abstract: The present invention relates to a method of directly trading products using an Internet-based community, in which each member registers an area, associated with both products that may be directly traded by the member and the member's traffic line, as a possible direct trading area. In the method, a management server receives a possible direct trading area from a terminal of a relevant member and stores information about the possible direct trading area in a database. The management server transmits information about a neighbor member who registered an identical possible direct trading area to the terminal of the relevant member. When a request to view information about a product registered by the neighbor member is received from the terminal of the relevant member, the management server extracts information about the product from the database and transmits the extracted product information to the terminal of the relevant member.
