Clarence Saunders revolutionized the way people shopped. He developed “self-service” grocery shopping in his Piggly Wiggly stores at a time when store assistants usually collected products for their customers. By introducing checkouts, clearly priced goods, and itemized receipts, he set the foundations for the supermarkets of today. Mike Freeman is the author of Clarence Saunders & the Founding of Piggly Wiggly: The Rise and Fall of a Memphis Maverick.
