Finding cheap gas in Chattanooga (37421)
The 37421 ZIP is anchored by Hamilton Place, the enclosed mall that sits at the center of a sprawling 200-acre retail complex just off I-75 in East Brainerd. That retail gravity, plus the interstate, makes this one of the busiest commercial corners in the Chattanooga area, and the fuel options reflect it.
Stations cluster thick around the Hamilton Place interchange and along East Brainerd Road, where mall and big-box traffic keeps competition lively and posted prices honest. With three interstates converging near Chattanooga, the corridor catches a lot of through-drivers between Atlanta, Nashville, and Knoxville, so the pumps right at the ramps tend to run a touch higher than those a block into the retail district.
Tennessee's fuel taxes sit below neighboring Georgia's, which is one reason southbound travelers often fill up on the Chattanooga side before crossing the state line. For locals, the grocery and warehouse fuel away from the immediate interchange usually shaves a few cents off the convenience-store price.

How to save more on gas in Chattanooga
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 Tennessee
Tennessee sits on PADD 2 pipeline supply with major terminals in Memphis, Nashville, and Knoxville, drawing fuel from Marathon Catlettsburg Kentucky and Valero Memphis (a 195,000 barrel-per-day refinery on the Mississippi River). The state gas tax is around 27 cents per gallon. Nashville, Memphis, Knoxville, and Chattanooga all see relatively competitive pricing. Costco, Sam's Club, Murphy USA at Walmart, and Kroger Fuel lead on value across Nashville, Memphis, Knoxville, and Chattanooga metros. Buc-ee's has expanded into Tennessee at the Crossville and Sevierville locations and pulls aggressive low pricing. Eastern Tennessee near the Virginia and North Carolina borders sometimes tracks the Appalachian regional pricing rather than Nashville averages.
