The U.S. average price of gasoline at $2.80 today, the national average is at its lowest level since December 2010 according to GasBuddy.

In 2011 for example, the national average went from $3.32 on the Wednesday before Thanksgiving to $3.28 on the Monday immediately following.

“Given the inventory reported by the Dept. of Energy and the supply build following last week’s snow storms, we anticipate that retail gas prices in most parts of the country will show another decline this week, even though millions of us will be driving for Thanksgiving,” said Patrick DeHaan, senior petroleum analyst with GasBuddy.  “It may seem counter-intuitive, but, it’s been a very unusual year.”
