TMK - The "regular gas" at Sam's Club in Iowa contains ethanol. This designation should only be used for fuel that is not mixed with ethanol - hence the 2 fuel types at Sam's should be mid-grade and premium and then diesel also - when supplied.
Costco in West Des Moines is my preferred gas station. Usually best price in metro area and always clean and neat.
They're stand alone gas pumps. Not really a "station"
Overall many of the stores that I visit seem to not take pride in clean restrooms!
Mens bathroom stalls are filthy! Doesn't look like they have been swept or mopped for some time.
Always good and friendly service
its ok
Great location
Friendly staff, clean, good selection
