21st century
In 2000, another store opened in Flanders; it closed in 2002, two years after its opening. Weis returned to Flanders in 2014, in a former A&P store adjacent to the location of its first Flanders store.[17]
In 2009, Weis expanded into the Southern Tier of New York with the acquisition of the 11-store Giant Markets chain.[18] Weis closed one former Giant Market in Binghamton in 2012, along with two others in 2014. Eight former Giant Markets continue to operate.[19]
In 2012, eastern expansion continued as Weis acquired three former Genuardi's stores from Safeway, in the Philadelphia suburbs of Conshohocken, Doylestown and Norristown, on June 16. A former Superfresh store in Towson, Maryland, opened as a Weis in 2012. Weis entered central New Jersey with the purchase of a former Pathmark store in Hillsborough in August 2013.
In November 2013, Weis opened its closest store to Philadelphia following its acquisition of a former Pathmark store in Huntingdon Valley, Pennsylvania. In July 2015, Weis purchased the location and assets of Nell's Shur-fine Market from C&S Wholesale Grocers in Penn Township, York County, Pennsylvania and followed that up in October 2016 with the purchase of a second Nell's location in East Berlin, Pennsylvania.[20][21]
Robert F. Weis, the son of Harry Weis, died in October 2015 at the age of 96. A philanthropist, Weis donated millions of dollars to charities, food banks, and other organizations in Sunbury, the Central Susquehanna Valley, and elsewhere. A strong supporter of Israel, he sponsored a flight of Jewish survivors of the Chernobyl disaster to make aliyah, and served as treasurer of the Sunbury chapter of the United Jewish Appeal. Weis was a member of Sunbury's Congregation Beth El and he helped found the Department of Judaic Studies at Yale University.[22]
In May 2016, Weis Markets announced the purchase of five stores from Mars in Baltimore County, Maryland, after that chain announced it was closing all its stores.[23] In July 2016, it was announced that Weis Markets entered into a purchase agreement with Ahold and Delhaize Group for 38 Food Lion locations in Maryland, Delaware, and Virginia as part of the divestiture of stores to gain clearance from the Federal Trade Commission for the impending Ahold/Delhaize merger.[24] The company completed the acquisition and conversion of the stores in early November 2016. On March 9, 2017, Weis Markets opened a 65000 sqft store in Hampden Township, Pennsylvania, that features a pub, ice cream parlor, expanded takeout food selection, a drive-thru pharmacy, and a beer cafe selling 900 varieties of beer and 500 varieties of wine.[25] In late September 2019, Weis acquired two Thomas' Food Market stores, one in Dallas, Pennsylvania and another in Shavertown, Pennsylvania, reopening the Dallas location under the Weis banner and closing the Shavertown location.[26]
On July 19, 2018 Weis Markets opened a second store in Morris County NJ in the town of Randolph (where a former A&P used to operate before A&P's bankruptcy in 2015).[27]
