A training module trains the customer's employees on proper techniques and procedures regarding cart retention. A cleaning, repair and maintenance module provides cleaning, repair and maintenance of the shopping carts. A cart retrieval module is utilized for retrieving the shopping carts if the carts leave the customer's parking lot. The use of the anti-theft shopping carts optimizes the available useful floor space by reducing the required cart inventory.
