Abstract: The present disclosure relates to a system, method, and computer program for matching products across merchants and updating registries based on other users' actions. A registry product database is maintained with product records that correspond to items that have been added to users' registries. Information is received related to a new registry item added to a user's registry from a merchant source. The system determines whether the new registry item matches a product record in the registry product database. If no match, a new product record is created for the new registry item and associated with a new merchant offer. If a match, the registry item is associated with the matching product record and the associated merchant offer is updated. The registries of all users in the system having a registry item matching the product record are updated to reflect a new merchant source or a different valid price.
