After a fairly steady decline over the last month in Tacoma, prices jumped up again in this market to an average of $4.148 a gallon according to The News Tribune’s Gas Price Tracker/
Meanwhile, the national average for gasoline prices declined from $3.792 last week to $3.739 this week.
Analysts attribute the difference in price changes to the Northwest’s relatively isolated market.
Unlike many states in the East and Midwest, the Northwest isn’t connected to the web of product pipelines that serve those states.
Gas is still available for less than $3.90 a gallon at at least two locations, the Costco near the Tacoma Mall and the Safeway at South 38th Street and South Sheridan Avenue.
