WASHINGTON (AP) — It's the gift that keeps on giving. Gas prices have fallen to the lowest level since May of 2009 at an average of $2.32 a gallon.

That's according to Triple-A spokesman Michael Green, who adds prices have fallen 92 straight days -- which has never happened before. Missouri is the first state since 2009 to see an average of under $2.00 per gallon at $1.98.

Green thinks the price of gas could fall another dime before leveling off next month.
