EAST ISLIP - The hours-long lines have eased at most Long Island gas stations, but now drivers are dealing with another headache at the pump: sky-high prices. Prices have begun to dip slightly, but many stations are still charging close to $5 per gallon. New York Attorney General Eric Schniederman is warning station owners that price gouging is illegal. Michael Watt, executive director of the Long Island Gasoline Retailers Association, says station owners have been paying more for gasoline from their wholesale suppliers. He says many are also looking to recoup costs from being closed for several days after Superstorm Sandy hit.
