The Big-Store MET was originally developed by the Canadian occupational therapist Danielle Jensen. We continued this work to develop a standardized version of the MET that could be administered in multiple large department stores that might be found in many countries around the world. Stores in which the Big-Store Met could be administered must (1) sell cards and ideally have a value card rack as well as regular card racks, (2) sell magazines or newspapers; (3) have at least two specialty services (e.g., photo centre, pharmacy etc.); (4) have a return policy that allows for immediate returns after purchase; and (5) have baskets and/or trolleys available for customer use.
