Costco in St Peters (101 Costco Way)

no window cleaning equipment or paper towels to check oil

usually the cheapest price in town. 93 octane premium most other places only have 91 octane

Gas prices are normally pretty good.

Great gas prices compared to everything else right now :)

Best place ever to buy fuel. Line moves fast and cheapest price around!

This station is always busy unless you catch it first thing when they open. Prices are cheapest in the area but only with membership.

why is had at this Costco $.21 per gallon more than South County? Seriously.

best price saved $3.00 over other stations

Busy but cheap if youre a Costco member.

Always the best prices!
