This low-cost kiok system incorporates modular components which assemble to form a merchandising enclosure. The components are designed to be interchangeable and are product specific. Storage is provided in each module. The optional roof structure is supported by modules which can be placed in the corners or "in line". Display cases can be slatwall, shelving, glass, or solid, depending on the particular merchandising situation. The system allows the kiosk to "grow" or be divided as business expands.
