Henry, however, suffered a fatal heart attack on December 25, 1979 and didn't live to see the ground broken on the new complex. Bob Minyard was named president of the company. In August 1981, the corporate headquarters and distribution center moved to a facility in Coppell, between the cities of Dallas and Fort Worth. By its 50th anniversary in 1982, the company operated 53 stores. That same year, a new concept store, the Sack 'n Save Warehouse Food Store, was introduced. The store, located in Haltom City, offered products in bulk at reduced prices. This new concept was considered necessary to remain competitive in the grocery industry, which faced slow growth during the mid-1980s. In 1987, Minyard purchased 24 stores from Safeway Stores, Inc., which exited the Dallas-Fort Worth market. This boosted the company's presences in the area. A total of 12 stores were bought in Dallas County, nine in neighboring Tarrant County, and three in other counties. Minyard was able to reopen all 24 stores within a record five days. By the end of 1987, the company owned and operated 62 Minyard Food Stores and 10 Sack 'n Save stores. Less than a year after the major acquisition, Chairman and CEO M.T. "Buddy" Minyard died of a heart attack. Leadership of the company passed to his two daughters, Lisbeth "Liz" Minyard and Gretchen Minyard Williams and CEO J. L. "Sonny" Williams  In 1990, the company announced that it would open a new store format dedicated to the growing, mostly under-served minority population in ethnic neighborhoods. Operating under the name Carnival Food Stores, ethnic merchandise was offered in addition to traditional grocery products depending on the neighborhood it served. Three Carnival Food Stores opened in Fort Worth in the summer of 1990. Two catered to African Americans and one focused on Hispanic shoppers. The concept proved to be successful and Minyard announced plans to open four additional Carnival Food Stores by late 1991. A total of 21 Carnival stores were operating by the end of the decade. The 1990s were a period of increased competition in the Dallas-Fort Worth area grocery market. In addition to longtime competitors such as Kroger and Tom Thumb, new chains were also entering the market. The most notable entrant was North Carolina-based Food Lion, which planned on opening 50 stores in the area. Minyard focused on improving customer service to deal with the growing competition. Store expansion slowed, although new stores were opened in strategic locations.
