The Hamilton (1250 Route 33) and Flemington (325 Route 202) stores will open in November. The other two are slated to welcome their first customers in the first half of next year, ALDI Center Valley Division Vice President Bob Grammer said. The Old Bridge store will be located near the site of a closed Pathmark store on Route 9, Grammer said. The location of the Egg Harbor Township store was not disclosed. Meanwhile, Aldi is holding a hiring event Wednesday for its current stores as well as the four new stores.
