Average retail gasoline prices in Savannah have fallen 4.0 cents a gallon in the past week to $3.53 a gallon on Sunday, according to GasBuddy's daily survey of 262 gas outlets in Savannah.
The national average has fallen 1.9 cents a gallon to $3.61, according to gasoline price website GasBuddy.com.
Prices Sunday were 31.6 cents a gallon lower than the same day one year ago and are 18.7 cents a gallon lower than a month ago. The national average has decreased 10.3 cents a gallon during the last month and stands 28.1 cents lower than a year ago.
"For the first time in a decade gasoline prices are going to be lower at the end of March than the beginning," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "GasBuddy data shows that the last time this happened was in 2003 when prices fell a nickle between the start of the month and the conclusion.
"Essentially what we're seeing here this month is perhaps the largest monthly decrease ever during the month of March, a month that has almost always seen prices finishing the month substantially higher than where they entered."
