One of the largest whole grocery distributing firms in southwest Kansas, lasting through World War II, was the Guymon-Petro Mercantile Company. Started in 1902 as the Gonder-Petro Mercantile Company at 225-227 S. Main, it was incorporated as Guymon-Petro in 1907. In 1938, it purchased the Winfield Wholesale Grocery, and by 1946, the company covered five-eighths of Kansas. – Kansas Historical Society (National Register of Historic Places submission)
