BOSTON (AP) - The cost of a gallon gas in Massachusetts is up another 3 cents, and has now jumped 8 cents in the past month.
AAA Southern New England reports Monday that the average price of a gallon of self-serve regular is up to $3.38 in the past week.
That's 11 cents higher than the national average for the same grade, but still 16 cents lower than the in-state price at the same time a year ago.
AAA found self-serve regular selling as low as $3.28 per gallon and as high as $3.59 per gallon.
