Nationally, prices have dropped 12.2 cents per gallon over the last month and stands at 5.5 center per gallon higher than one year ago, the agency reported.
"The national average has continued to see a steady decline over the last week, and that trend will likely continue through this week at the very least," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan.
"Last week, the Energy Information Administration reported one of the largest single week increases in gasoline inventories in my recent memory, which will likely contribute downward pressure to wholesale gasoline prices in the days and perhaps weeks ahead," DeHaan said.
