Sams Club - Pecos is the old school Sams location in Vegas. It doesn't have gas pumps or car washes. Some people think the location can be sketchy as it's not Summerlin. But if you want to get in, get what you want and not fight a horde of people most of the time to do it, this is the location to shop at.
My family in one form or another has held a Sams Club membership since they opened their 2nd location in Missouri 30 years ago. Some gripes about Sams Club never change and certainly apply to the Pecos location. Checkout can be slow. They don't always restock the carts. And why do they make the cashiers lift every single flat of water out of the cart? Beyond all that this location isn't flashy but it's one of the better locations I've seen in 14 states. Why? The shelves are stocked, the place is clean, and while you may have to wait in a line or two the staff will help you if you need it.
(Tip: The WalMart Money Services ATM has a weird $300 limit for cash transactions while most other places are $400).
4 Stars.
