Would you like to put an extra $550 in your pocket this year?That’s how much the U.S. government estimates Americans will save in gasoline costs in 2015 with the current drop in prices.It’s hard to believe, but the national average for a gallon of gasoline was more than $1 a gallon higher at the start of 2014 than it is today, according to GasBuddy.com. That includes Tennessee prices as low as $1.69 a gallon in Ocoee, and $1.76 in Memphis.In Warren County, gasoline has dipped below $2 a gallon.Kidd Ford owner Terry Kidd says the lower gas prices haven’t created a run on larger vehicles, but the lower prices are certainly appreciated.“I think people are cautiously optimistic because there’s the feeling gas prices won’t remain this low,” said Kidd. “It will take four to six months of consistently low prices for people to feel like it’s going to stay this way for awhile.
