The average price of gasoline in Maine went up by less than a penny per gallon in the past week. That remains about where it was one year ago. The gasoline pricing website GasBuddy.com says drivers in Maine are paying an average of $3.49 a gallon for gas. The average price of gas nationally increased by just over two cents since last week, to $3.23 a gallon. Prices in Maine are less than half a cent higher than they averaged last year at this time. Prices in Presque Isle range from 3.61 to 3.64. Analysts say they expect gas prices will increase slightly but next year will average less than they have throughout 2013.
