Gas prices are going up, but they are cheaper here than in most parts of the United States. Only three states are selling a gallon of regular-grade gas cheaper than stations in Minnesota, according to the national motoring club AAA.

According to an overnight survey of 2,168 filling stations statewide, the average price for a gallon of gas in Minnesota is $3.03, that's 13 cents cheaper than the national average of $3.16. Only Missouri at $2.978, New Jersey at $2.972 and Wyoming at $3.008 had a lower price per gallon than Minnesota, AAA said.

The average price for a gallon of gas in the Twin Cities is even lower than the state average. According to a survey of 983 stations in the metro area, the average price of a gallon of gas was $2.974.

Prices in Rochester averaged $3.052 while it was $3.063 in St. Cloud and $3.088 in Duluth, AAA said.

That might seem high, but it could be considered a bargain if predictions of gas selling at $4 per gallon this summer come true.

The most expensive places to buy gas are in Oregon and New York. Motorists there are shelling out $3.32 per gallon, AAA said.
