Pump prices increased again this week by just less than 4 cents, although the state remains one of the cheapest places to purchase fuel.
Triple-A Arizona reports the national average went up by 3.6 cents to $3.461 a gallon. Tucson was at the low end at $3.343 a gallon while Flagstaff remained the most expensive place in Arizona to purchase gas at $3.595 a gallon.
Even with the jump, Arizona is still the ninth-cheapest state to fill the tank. The increase was also almost a penny less than the 4.5 cent increase in the national average, which is up to $3.657 per gallon.
