The system operates through a computer platform connected to an internet social network. A user can share information about an item through the network by providing it to the platform using a communications device connected to the network. If a similar or identical product corresponding to the item is available for purchase through the system, a link is created between the item and the product and the item is shared on the platform in digital media, such as an image of the item, selected by the sharing user. Other users can access the platform through the network using a communications device, view the image of the shared item, and purchase the available product. The sharing user is rewarded for sharing the item, regardless of whether or where the product is purchased. Both the sharing user and the purchasing user are rewarded if the product is purchased using the system.
