According to this week’s Triple-A East Central gas price report, the average price of gasoline across Western Pennsylvania is a penny cheaper this week at $2.74. In Beaver, the average is at  2.67 a gallon while drivers in New Castle are paying a penny less at 2.66. Slowly but surely, gas prices continue to trend cheaper with half of all states seeing pump prices drop two-cents on the week. This caused the national average to push cheaper by a penny down to $2.56. The average is 11-cents less than a month ago and 28-cents cheaper than a year ago.
