WinCo Foods isn't just big on self-service -- it's giant. Inside the immense stores (average size is 85,000 sq. ft.) of this mostly employee-owned supermarket chain, customers shop for food in bulk and bag their own groceries. The company's 40-plus stores also feature pizza shops, bakeries, health and beauty products, and organic foods. WinCo Foods, formerly known as Waremart Foods, was renamed as a shortened version of "winning company." The name is also an acronym for its states of operation, which include Washington, Idaho, Nevada, California, and Oregon. Founded in 1968, WinCo Foods formerly operated stores under the Cub Foods and Waremart names. Employees own more than 80% of the company.
