If you live in the Northwest or the Centennial Hills area, the Costco Wholesale at 6555 N Decatur Blvd is likely your second home. It’s a massive warehouse that’s a total lifesaver for stocking up on everything from those legendary rotisserie chickens to bulk paper towels. Compared to the sometimes-chaotic Summerlin location, this "Centennial" spot is a favorite for many of us locals because the aisles feel a bit wider and the overall vibe is just a little more laid-back, even when it’s busy on a Saturday morning.
One of the biggest perks here is the Costco Gas Station. It opens much earlier than the main warehouse, which is great if you want to beat the rush and fill up your tank before the morning commute. Inside, the "Treasure Hunt" aspect is real—you might walk in for milk and eggs and walk out with a new air fryer or a giant outdoor gazebo. Plus, for Executive Members, the early access hours are a game-changer if you want to get your shopping done and be back home before the crowds really start to pour in.
What really distinguishes this location is the variety of services all under one roof. They have a top-notch Tire Service Center where you can get your tires rotated while you shop, and a Pharmacy that’s known for being fast and having great prices. If you’re a foodie on a budget, you already know the Food Court is the ultimate finale to any trip. You can’t beat a $1.50 hot dog combo or a massive slice of pizza to reward yourself for navigating the warehouse.
The store is open every day, but the hours for the gas station and the main warehouse are a bit different, so it’s good to keep track. As of early 2026, the standard hours for the Centennial warehouse are:
Monday – Friday: 10:00 AM – 8:30 PM (Executive Members often get in at 9:00 AM)
Saturday: 9:30 AM – 7:00 PM (Executive Members often get in at 9:00 AM)
Sunday: 10:00 AM – 6:00 PM (Executive Members often get in at 9:00 AM)
Gas Station: Mon–Fri 6:00 AM – 10:00 PM; Sat 6:00 AM – 8:30 PM; Sun 6:00 AM – 8:00 PM
Whether you’re a parent buying in bulk for a big family or a local small business owner grabbing supplies, this Costco makes the whole "big box" experience feel neighborly. It’s organized, the staff is helpful, and you always know you're getting a solid deal on quality stuff.
