Gas for less than $2 a gallon is getting easier to find.

AAA says 71% of U.S. gasoline stations are selling fuel under that level, and drivers in all but three states — Hawaii, Alaska and California — can find at least one place where they pay that little.

Moreover, more than 16,000 stations are selling gas for less than $1.75 per gallon, it added. The cheapest 1% are selling gas for an average of $1.56.
