In particular embodiments, a user enters a code received at a point of sale identifying a node on a social network representing the point of sale. Upon entering the code into a mobile application, the application requests the user to identify other users that referred the user to the point of sale. Upon selecting one or more referrers, the social networking system applies one or more policies to the selected referrers. In particular embodiments, the social networking system integrates with online merchants, and prompts a user to select users or nodes that referred the user to the site or the specific product. In particular embodiments, the social networking system tracks the value of every single transaction, and may generate a list of the top ten value generators for a given node. |
