Keedoozle was the first fully automated grocery store in the United States, a vending machine concept developed by grocer Clarence Saunders in 1937. It is often held that the name "Keedoozle" was coined by Saunders to refer to the technology used, in which a "Key Does All" for the grocery shopper, but another interview with Saunders appears to contradict this.The Keedoozle concept was intended to be a grocery shopper labor-saving and cost-saving device. These groceries were offered at a cost of 10% - 15% below the going rate. The Keedoozle store sold mostly dry goods at a half a penny to three cents over cost. Saunders developed this concept from his self-service Piggly Wiggly grocery store concept.
