(NewsDakota.com/PPR) – The average price of a gallon of gasoline in North Dakota stands at $3.41.

GasBuddy.com says that’s up by about one and a half cents over last week. That price is more than 5 cents per gallon lower than a month ago.

The national average is $3.55.

GasBuddy petroleum analyst Patrick DeHaan says the prices are due to some refinery issues and a low gasoline supply, but he doesn’t think that trend will last too much longer.

The cheapest gas in North Dakota is $3.19, while the most expensive is $3.61.
