Walmart sells groceries and general merchandise through stores and online. Its operations include Walmart retail formats and membership-based Sam’s Club, supported by delivery and pickup services.
History and development
Sam Walton opened the first Walmart store in Rogers, Arkansas, on July 2, 1962. A local discount retailer developed through stores and distribution into a broad retail group. Its online activities build on that longer business of sourcing goods and delivering them to consumers.
