Top 5 Gas Stations & Cheap Fuel Prices in Custer, SD

Surprisingly clean bathrooms. Advertised prices are cash prices.

Friendly staff just hate when cash and credit are different prices

Nice station convenient to the highway. My only complaint - beware of tricky pricing!! The 85 octane (usually cheapest) was actually the highest price!! Mid-grade was 30¢ more than the lower grade! Unfortunately we had already pumped $165 into our RV before we caught this. 🤬

Good quick stop

Hint: Do your grocery shopping at Dakotamart Grocery first and use your receipt to save cents-off per gallon at the pump. We got 10 cents off/gallon with our $137 receipt!
