12145 Rockville Pike (Pike Shipping Center), Rockville, Maryland; and 6300 New Hampshire Ave., Takoma Park, Maryland. By 1969, the Alabama Ave store closed and eight stores remained. By 1978, the River Terrace, Michigan Ave., District Heights, and Naylor Rd., S.E., stores were closed. On August 23, 1978, the last new Jumbo Food Store opened at Little River Turnpike and John Marr Drive (4223 John Marr Dr), Annandale, Virginia. In 1978, Jumbo also opened the first Shoppers Food Warehouse (SFW). The two remaining Herman brothers opened the first Shoppers Food Warehouse in 1978 as a foray into the warehouse supermarket business. Levin died before Shoppers was conceptualized. The original concept brought the Washington area its first non-membership chain in the area to offer an expanded selection of large-packaged (or "warehouse-sized") products at a lower, bulk price. Shoppers eliminated all but two to three sizes of each product to allow a greater selection of different brands on a typical shelf and to further lower prices. Using warehouse shelving and leaving packaged goods in their boxes on the shelves enabled a reduction of retail labor that also allowed a much lower price to be passed to the consumer. Since changing hands from the company founders, it has developed into a more conventional supermarket model with more conventional pricing. The SFW at 3255 Little River Turnpike in the Brighton Mall, Alexandria, Virginia, opened in 1980. By 1983, there were three additional SFWs at 9195 Central Ave. (Hampton Mall), Capitol Heights, Maryland; Rt 108 & Georgia Ave (Village Mart Shopping Center), Olney, Maryland; and Little River Turnpike and Pickett Rd., Fairfax, Virginia. In 1985, when Jumbo / Shoppers became the third-largest chain in the DC area, eight SFWs and four Jumbos (Rockville, Takoma Park, Adelphi, Md., and Annandale, Va) were in operation. In 1986, there were 13 Jumbo or Shoppers locations with the Chantilly, Virginia, and Clinton, Maryland SFW locations opening that August. By 1989, when Herbert Haft acquired half interest in the Jumbo Food Stores chain, 18 Shoppers Food Warehouse locations were in operation and the Jumbo Food Store name was gone. With the success of the Shoppers format, all Jumbo stores were eventually converted to Shoppers. In 1988, Irving and his son and vice president, Mike Herman, made the decision to retire, leaving Kenneth and his children in control of the corporation. In 1989, Irving sold 49 of his 50 percent of the
