You may have noticed: gasoline has been getting cheaper.

While the average price for a gallon of regular is about $2.20 in metro Atlanta today, a gallon can be had for as little as $1.88 today, according to GasBuddy.com.

The average price in metro Atlanta a year ago was about $3.38 a gallon, according to GasBuddy.

And Georgia is not even near the bottom of the price-pack in the Southeast: According to AAA, the average price is below $2 a gallon in Tennessee.

The good news for consumers is that more good news is coming, said Mark Jenkins, AAA spokesman.

Some of that is seasonal, but the biggest factor is generally the global price of oil, and that price has been dropping for more than a year.

“Gas prices below $2 a gallon will become more of a common sight in the southeastern United States,” he said. “Prices at the pump are typically their lowest during the fall and winter seasons, because fewer Americans take extended road trips, leading to declines in demand. Plus, oil prices are especially low right now due to a wealth in global supply.”

Compared to this time last year, motorists are currently saving $15 to $25 each time they buy a full tank of gas, he said.
