Average retail gasoline prices in Minnesota have fallen 10.8 cents in the past week, averaging $3.04 per gallon Sunday, according to GasBuddy’s daily survey of 2,856 gas outlets in Minnesota. This compares with the national average that has decreased 5.4 cents per gallon in the last week to $3.20 per gallon, according to gasoline price website MinnesotaGasPrices.com.

Gas prices in International Falls Sunday ranged from $3.17 to $3.19, according to the website.

Including the change in gas prices in Minnesota during the past week, prices Sunday were 21.7 cents per gallon lower compared to the same day one year ago and are 25.8 cents per gallon lower than a month ago. The national average has decreased 17.4 cents during the last month and stands 26.7 cents per gallon lower than this day one year ago.

“Gas prices across many communities are now the lowest since they’ve been since the Libryan crisis in February of 2011. Nearly 15 percent of all stations in the U.S. are now selling gasoline under the psychologically important $3 per gallon level,” said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. “Last year on this date saw just 1 percent of stations selling under that level, so motorists aren’t doing too shabby. States that saw the largest declines last week were Montana, Ohio, and Indiana, all where prices declined at least 15 cents per gallon. Several stations in Tulsa, Okla., which features the cheapest gas in the U.S. are selling at a mere $2.45 per gallon, a number so low that had you said that just six weeks ago, motorists would have been shaking their heads in disbelief. Prices nationally could drop to as little as $3.05 a gallon by Christmas,” DeHaan said.
