The national average price of a gallon of regular unleaded fell again by three cents to $2.48 to start the month of December, continuing a two week slide in prices, according to AAA.

Prices are the cheapest since early November, reports AAA.

 “Cheaper winter gas prices are being seen for the bulk of the country as gasoline demand hits the lowest mark since February,” said Jeanette Casselano, AAA spokesperson. “On the week, 90 percent of states saw their gas price average drop – some even by double digits.”

The states with the largest weekly decreases include Indiana (14 cents), Ohio (12 cents), Illinois (11 cents), and Michigan (9 cents).

Meanwhile, several states in the West Coast are paying some of the highest prices, despite the continuing nationwide price drop, including Hawaii ($3.28), Alaska ($3.23), California ($3.16), Washington ($2.98), Oregon ($2.83) and Nevada ($2.71), reports AAA.

Meanwhile, the average price of a gallon of diesel dropped 0.4 cents per gallon to $2.922, which is 44.2 cents higher than a year ago, according to the U.S. Energy Information Administration.
