Gas prices have fallen by more than 20-cents in Minnesota in September, and the statewide average is now a dime below the national average. Triple-A Minnesota’s Gail Weinholzer says we’re paying 52-cents less per-gallon than one year ago as well. She says Minnesota had the largest 2-week decline in prices in the nation also. Weinholzer says there’s ample supply, demand is flat, crude oil is going down and there haven’t been any hurricanes in the Gulf. The lowest price for gas in Minnesota is $3.09 per-gallon at a station in East Bethel, and the most expensive gas is $3.99 a gallon at a Brooklyn Center gas station. The average price per-gallon for regular unleaded in New Ulm is $3.39.
