Gasoline prices in Virginia have fallen by an average of seven cents per gallon since last month.
AAA Mid-Atlantic reports that the average price of a gallon of unleaded gasoline in Virginia was $3.17 Tuesday. That's down from $3.24 a month ago.
Virginians are paying 17 cents less than the national average.
AAA Mid-Atlantic spokeswoman Martha Mitchell Meade says prices are expected to continue to decline because of sufficient supplies, weaker demand, more affordable winter-blend gasoline and lower crude oil prices.
