A method and system for providing a transactional environment including a server and one or more set-top boxes in communication with the server. The server stores product information data, which is updated in the server as soon as the product information data changes. The set-top boxes receive the product information data as well as navigable displays in a single transmission, which guide a user through a product ordering process on his or her television. The user may navigate and complete the ordering process in a real-time basis using a television remote control. The product information, e.g., available inventory, is updated as soon as the product information changes, and the set-top boxes replaces outdated navigable page data on a real-time basis.
