Gas prices are unchanged this week as the holiday season draws near. Triple-A Arizona says gas prices remained at $2.23 this week on average across the state. In Flagstaff, gas was up nearly two-cents a gallon to $2.38 on average. Some stations are selling gas for $2.29 and lower. In Prescott, gas prices were up a cent-and-a-half on average from last week to $2.26 a gallon. Some stations are selling gas for $2.09 and lower. Even though prices leveled out, or even rose in some areas of the state, officials continue to say decreased demand for gas is pushing gas prices lower across the country.
