How to save more on gas in Ballwin
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 Missouri
Missouri sits on PADD 2 pipeline supply with the Phillips 66 Wood River refinery just across the Mississippi in Roxana, Illinois, providing roughly 350,000 barrels per day of supply to the St. Louis metro. The state gas tax is around 27 cents per gallon, on the lower end of the Midwest. St. Louis, Kansas City, and Springfield all see competitive pricing, with QuikTrip (founded in Tulsa but with strong Missouri presence), Costco, Sam's Club, and Casey's General Store leading on value across all three metros. The Kansas City Missouri-Kansas border creates an interesting pricing dynamic, with stations on the Kansas side sometimes running a few cents below the Missouri side because of different state tax structures.
