Driving to Grandma’s house for Christmas will cost you a lot less this year.
The national average for a gallon of gasoline is at its lowest holiday level since 2009.

The website GasBuddy reported the lowest price in Missouri on Tuesday (Dec. 22) was one dollar and 50 cents in Independence. Illinois drivers found the cheapest gas in Decatur at one dollar and 52 cents.

The reason for all the savings is that supplies are outpacing demand. Gas has fallen below two dollars a gallon in 30 states.

Industry observers say the downward cost trend could continue until spring, when demand usually rises and refineries switch to making a federally-required summer blend of fuel.
