Costco Gas Station, St Peters MO

Costco has the lowest price on gas in the area 99% of the time so it is often worth going out of the way to get gas here.

Their gas prices save you $. 10 to $. 30 per gallon. You need to be a COSTCO member. There is an attendant on duty if you need assistance.

Always clean and prices are generally $0.30 less than on the general streets. Always attendant there if you need help.

Great prices on gasoline but this Costco Gas Station is always crowded. I really wish Costco would expand this station to allow for more capacity and less bottlenecks.

Very crowded during peak times, but otherwise a very well-priced and maintained gas station. There are attendants always avaliable during open hours, which is nice. The only issue I had was solved when the card readers were changed. -1 star for being very busy, usually resulting in about a 10 minute wait.
