Finding cheap gas in Saint Marys (31558)
Georgia's last exit before Florida lands here, in Camden County on I-95 beside Naval Submarine Base Kings Bay, the Atlantic fleet's home port for ballistic-missile submarines. The base population and the steady churn of military families give the area reliable, year-round fuel demand.
Being the final stop before the state line, the interchange stations catch travelers timing fill-ups around the price gap between Georgia and Florida. Northbound drivers crossing up from Florida and southbound travelers facing a long haul both feed that interstate-adjacent market.
GA-40 handles the local flow east toward the base gates and the St. Marys waterfront, its pumps serving base personnel and residents rather than one-time travelers.
For everyday fill-ups, those GA-40 stations generally beat the spots planted purely to catch passing interstate traffic, which is why locals tend to skip the closest-to-the-ramp options.

How to save more on gas in Saint Marys
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

About gas prices in Georgia
Georgia's gas tax is roughly 33 cents per gallon, and the state benefits from the Colonial Pipeline, which runs from Houston refineries through Atlanta on its way to the Northeast and supplies a major share of Georgia's fuel. Atlanta's prices can spike sharply during pipeline disruptions, as the September 2016 leak demonstrated when prices jumped 30 cents in a week. QuikTrip, RaceTrac, Costco, and Sam's Club are the cheapest reliable picks across Atlanta, Savannah, and Augusta, with Murphy USA at Walmart locations consistently competitive in suburbs and smaller cities.
