Finding cheap gas in Des Moines (50315)
South Des Moines is a sprawling, working part of town that runs from the older south-side neighborhoods down toward Army Post Road near the city's southern edge. SW Ninth Street is the spine here, a long commercial artery lined with the everyday businesses and gas stations that serve this side of the river.
The Army Post Road area down south sees a lot of cross-town traffic and commercial activity, which supports a decent spread of high-volume stations. Where retailers are chasing that steady flow, regular prices tend to stay competitive, so the southern commercial pockets are usually a solid place to fill up.
Along SW Ninth, you will find the densest run of options, and comparing a few of them before committing is the simplest way to land the day's best price. The pumps tucked into the quieter residential streets off the main drag rarely undercut the busy arterial stations.

How to save more on gas in Des Moines
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 Iowa
Iowa is Casey's General Store country, with hundreds of locations across the state that typically run among the cheapest pump prices in the Midwest. The state gas tax is around 30 cents per gallon, plus Iowa's ethanol-friendly market promotes E15 and E85 blends that often run 10 to 30 cents below regular unleaded for compatible vehicles. Des Moines, Cedar Rapids, and Davenport see the most competitive pricing thanks to Casey's, Kum & Go, Hy-Vee Fuel, and Costco competing for membership cards. Rural Iowa cooperative stations (Co-op and FS Energy) are often surprisingly competitive due to direct grain-and-fuel distribution relationships.
