Gas prices continue to fall across the state. Triple-A Arizona says prices across the state are down about a cent a gallon from last week. In Flagstaff gas prices are down about a cent-a-half to $2.60 a gallon, however some stations are selling gas for $2.39 and lower. In the Prescott area, prices are down about four-tenths of a cent to $2.41 a gallon. Officials say prices should continue to fall as demand for gas falls as well.
