Kuhn's Quality Market, located in the Cranberry Mall on Route 19, will close its doors on Sept. 3.
The Kuhn's store opened in Cranberry in 2006. Assistant Manager Tim DeVictor declined comment on the store's closure.
The supermarket chain has eight other stores around the Pittsburgh region, including locations in Moon and the North Hills.
On Thursday, signs outside the Cranberry store advertised 25 percent off all merchandise (excluding milk and cigarettes) because of the store's closing.
