Gasoline prices have spiked in Massachusetts in the last week. 

Triple A reports that the average cost of a gallon of self serve regular gas climbed nine-cents in the last week to three-dollars and eight-cents. 

Despite the jump, a gallon of gas in Massachusetts is still 14 cents lower than the national average.  Last year at this time, a gallon of self serve regular gas was selling for an average of three-dollars and 43-cents in Massachusetts.
