Gas prices stayed relatively unchanged from last week across Arizona. Triple-A Arizona says the average price of gas was down about a half-cent to $3.05 a gallon. Spokesman Aldo Vazquez says “what we’re seeing nationwide is cheaper crude oil prices and stable and strong refinery utilization, which are contributing factors to keeping pump price jumps from being incremental.” In Flagstaff, the average price of gas was up a cent-and-a-half to $3.16 a gallon. Some stations are selling gas for $2.98 and lower. In Prescott, the average price of gas fell a cent from last week on average to $3.04 a gallon.
