The Susser family's gasoline business began when Minna Schwartz won the heart of an entrepreneur. In 1938 her husband, Sam Susser, took over operation of two service stations in Corpus Christi, Texas that Minna had inherited, and they began selling fuel to local companies. The business has flourished, and today, Susser is the largest non-refiner fuel distributor in Texas, supplying fuel to more than 2,400 convenience stores, service stations and commercial fuel customers in Texas, Oklahoma and Louisiana. Sam and Minna's two sons, Jerry and Sam J., joined Susser Petroleum Company in the 1960s. Together, they invented the first â€œpay-at-the-pumpâ€ system that allowed customers to purchase gasoline with a credit card from unattended stations. Sam J.'s son, Sam L. Susser, joined the business in 1988. The Company began building its retail convenience store business with the acquisition of 26 7-Eleven stores in 1988, and today there are more than 560 StripesÂ® convenience stores in operation.
