The average price of a gallon of regular fell to $2.14, down 8 cents from a week ago and $1.19 less compared with a year ago, according to the Department of Energy.

This is the lowest weekly average gas price since May 2009 - the recession at the time depressed prices dramatically.

GasBuddy predicts that the national average will fall to $1.95 by the next month.

As of now 43 states have at least one gas station selling gas for less than $2 a gallon, according to GasBuddy.
