Gas prices continue to fall, but it remains to be seen how much more it will drop after a major dive in oil prices this week. Triple-A Arizona says the average price of gas is $2.70 a gallon, which is nearly four-cents a gallon cheaper than last week. In Flagstaff, gas prices have fallen more than three-cents a gallon to $2.66 a gallon on average this week. Some stations are selling gas for $2.54 a gallon and lower. In Prescott, prices at the pump fell an average of nearly six-cents a gallon this week to $2.80 a gallon. Some stations are selling gas for $2.78 and lower. In Cottonwood and Sedona, you can find gas for $2.68 a gallon and lower. Officials say this time of year you would see increases at the pump, but with the decline of oil prices this week, most areas are still seeing a decline.
