A system of rendering content according to availability data for at least one item includes a server to receive a content request from a user and, in response, to retrieve requested content. A rendering engine coupled to the server identifies at least one rule associated with the content and concerning the item. A rules engine coupled to the rendering engine generates at least one availability request corresponding to the rule and concerning the item. The rules engine receives the availability data for the item, retrieves additional content according to the availability data for the item, the additional content selected from among one or more stored content elements that concern the item, and communicates the additional content to the rendering engine for incorporation into the requested content. The rendering engine renders the requested content, including the additional content concerning the item.
