Massachusetts gas prices down 3 cents per gallon; remain a penny above the national average

The price of a gallon of gas in Massachusetts has dropped 3 cents in the past week.

AAA Southern New England reports Monday that self-serve regular is down to $3.67 per gallon.

That's a penny more than the national average, 3 cents higher than the in-state price a month ago and a full 19 cents higher than at this time a year ago.

AAA found wide range of prices, from a low of $3.45 for a gallon of self-serve regular to a high of $3.89 for the same grade.
