Gas Buddy app can help find cheapest prices for Thanksgiving travel

Gas prices are down across the country right now, which is good news if you plan on driving to visit friends or family for Thanksgiving.

Depending on which way you are going, you might want to fill up before you leave, says Patrick DeHaan, Head of Gas and Petroleum Analysis at Gas Buddy.

"Generally, if you are heading out of the state, wait until you cross out of Florida to fill up," he says.

But if you are heading south to places like Miami or the Florida Keys, you'll want to get your gas before you get too far south, because that's where the prices are the highest.

Although prices are down right now across Florida, states like Georgia, South Carolina and Alabama are generally going to be cheaper to top off your tank, DeHaan says.

GasBuddy.com is a website with a free app that directs you to the most affordable gas stations in your area. But DeHaan says as a general rule in the Southeast, the farther south you go the higher the gas prices get.

DeHaan says in Georgia into the Carolinas it can be anywhere from 10 to 15 cents cheaper per gallon than Florida. Gas Buddy can help you find the cheapest prices no matter where you go.
