E-Z Mart Stores founder Jim Yates kept his first convenience store in Ashdown, Arkansas, open until 11. The company now boasts 300 outlets across five southern states (Arkansas, Louisiana, Missouri, Oklahoma, and Texas). Rather than build its own stores, the company usually expands through acquisitions. In addition to the standard hot dogs, chips, sodas, and cigarettes, most E-Z Mart locations also offer Shell, Conoco, Phillips 66, or CITGO gasoline. Yates died in late 1998 when the plane he was piloting crashed, leaving his daughter Sonja Hubbard at the company's helm as CEO.
