Pathmark Stores, Woodbridge, N.J., reported that its sales for the first quarter ended May 4, down 7%, were impacted by the sale or closure disposition of its 36 freestanding drug stores, which generated sales of $400,000 in the quarter and $45.5 million a year before. Supermarket same-store sales fell 3.5%, due in part to inclement weather and numerous store openings and remodels by competitors, Pathmark said.
