It was an anticipation for many comparable to ticket sales for the greatest band on Earth. At 4 a.m. Thursday, the line outside the new Bottom Dollar Food at County Line Plaza in Hilltown Township was nearly 100 deep. By the grand opening ribbon cutting at 8 a.m., more than 400 were walking through the doors. Store manager Jeff Katz said the first 200 customers received free groceries Thursday. Bottom Dollar Food offers double back guarantees on produce and meats, and will under match competitors' prices by one cent.
