You might say Sheetz is to the convenience store business what Wal-Mart is to discount shopping. Noted for being exceptionally large (stores average 4,200 sq. ft., nearly twice the size of the average 7-Eleven, but new stores are as large as 5,000 sq. ft.), Sheetz stores sell groceries, fountain drinks, baked goods, and made-to-order sandwiches and salads, self-service car washes, as well as discount gas and cigarettes. The company operates more than 435 combination convenience stores and gas stations. More than half of its stores are in Pennsylvania, but also in five other states. Founded in 1952 by Bob Sheetz, the company is owned and run by the Sheetz family.
