How to save more on gas in Charleston
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.

About gas prices in South Carolina
South Carolina sits on the Colonial Pipeline mainline, which supplies most of the state's gasoline from Gulf Coast refineries en route to the Northeast. The state gas tax is around 28 cents per gallon. Charleston, Columbia, Greenville, and Myrtle Beach all see relatively competitive pricing, with the coastal cities sometimes benefiting from direct tanker shipments through the Port of Charleston. Costco, Sam's Club, Murphy USA at Walmart, Sheetz (with strong Upstate presence), and Wawa (entering the market) lead on value across Charleston, Columbia, Greenville, and Myrtle Beach. Hurricane season can disrupt Colonial Pipeline operations and cause statewide price spikes, particularly when storms shut down Houston-area refineries that feed the pipeline.
