Harry and Sigmund Weis founded Weis Markets in 1912, when they opened a small neighborhood store known as Weis Pure Foods on Market Street in Sunbury, Pa. They were among the first grocers to sell goods on a cash and carry basis during a time when most stores sold goods on credit. Weis Markets is a publicly traded company that operates more than 150 stores in Pennsylvania, Maryland, New Jersey, New York and West Virginia. Its banners include Weis Markets, Mr. Z's, King's and Scot's Lo-Cost. The company employs approximately 18,000 associates and also operates a more than 1 million-square-foot distribution center. In addition, it operates dairy, meat processing and ice-cream plants. Weis Markets is one of the largest purchasers of Pennsylvania produce and dairy products. The company maintains locations in cities throughout the United States, including Muncy, Pa.
