In this Wednesday Sept. 24, 2014 photo, a customer reaches for the regular switch to fill her tank with the $2.92-a-gallon regular gas at a RaceWay gas station in Richland, Miss. The typical autumn decline in gasoline prices is getting a big push lower by falling global oil prices. By the end of the year, up to 30 states could have an average gasoline price of under $3 a gallon. (AP Photo/Rogelio V. Solis)
