US retail gas prices dropped nearly 24 cents a gallon in the past two weeks, according to a national survey.
It's the third consecutive decline since a mid-August peak.
The Lundberg Survey says the national average for self-serve regular was about two dollars, 42 cents on September 22nd, down from about two-65 two weeks earlier.
Gas prices peaked August eleventh at just over three dollars and have dropped about 60 cents since that time.
The lowest average price in the survey was notched in Des Moines, Iowa: two dollars, seven cents a gallon for regular.
The highest was in Honolulu, at three-oh-three.
