Sam's Club in Castle Rock (5940 Promenade Pkwy)

Always the lowest price near us?

Great views, cheap gas, but always windy!

I wish they would make the Diesel pumps…Diesel only lines. They lines are always ridiculously long with people getting Regular gas. Most of the time I just leave!

lowest prices and great customer service!

Great value! Among the top 10 places in South Denver to fuel up. GasBuddy Premier membership ($10/month) provides additional 20¢/gal discount.

Only place I get gas. The savings more than pays for the membership. Now ... if only customers whose gas caps are on the driver's side would stop pulling up to the passenger side pumps and breaking the retractor line by trying to stretch the pump handle to the other side of the car, this place would be even better. Pumps are constantly out of service due to this. If you have small sedan, go for it, but maybe skip that idea with your 6,000 lb SUV.

Great customer service and cheapest prices in town!

Always a Great place and the Best Prices

Very clean, well lit, and rarely crowded. The attendant is friendly and is readily available if needed.

You just have to be a member. Love the savings.
