Gas prices across Arizona are unchanged this week. Triple-A Arizona says the average price of gas in the state remains at $3.15 a gallon. Triple-A spokesman Aldo Vazquez says expect prices to stay the same over the next couple of weeks. He says “while supplies have tightened due to a slow recovery from Hurricane Ida, this is also the point where gas demand starts its seasonal decline.” Vazquez adds, “and while there may be some fluctuation, we expect most motorists to see stability at the pump.” In Flagstaff gas prices are up a cent-and-a-half this week on average to $3.44 a gallon. Some stations are selling gas for $3.31 and lower. In Prescott, the average price of gas is up a cent this week to $3.15 a gallon. Some stations are selling gas for $3.03 and lower.
