Average retail gasoline prices in Yakima have fallen eight-tenths of a percent per gallon in the past week averaging $3.67 per gallon according to GasBuddy's daily survey of 91 gas outlets in Yakima.

This compares with the national average that has fallen 5.8 cents per gallon to $3.43 per gallon in the same time frame.

Prices are 32.0 cents per gallon lower than the same day one year ago and are 2.4 cents per gallon higher than a month ago. The national average has decreased 18.8 cents per gallon during the past month and stands 36.6 cents per gallon lower than this day one year ago.

"Gasoline prices continue to erode with 12 states that are seeing prices under $3 a gallon and more states will join in on that over the next seven days" said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan.

"While it's generally good news that gasoline prices continue falling, many Americans don't believe we're likely to see national averages drop under $3 per gallon over the next year at the pump," DeHaan said.

GasBuddy surveyed more than 10,000 motorists with two-thirds of respondents saying that the national average will remain between $3 and $4 per gallon through 2014.
