When we first covered this location in October 2024, construction was still underway. A year later, the new Costco Wholesale on the Allen–McKinney border has been serving Collin County shoppers since its August 2025 debut. The once-vacant site has quickly become one of the region’s busiest retail spots.
From Construction to Reality
The transformation from open land to full-scale warehouse wrapped up earlier this year, adding another major anchor to the booming corridor north of Dallas. The store features a gas station, tire center, pharmacy, and bakery—standard offerings that continue to draw steady crowds. Despite a few growing pains, the store’s location has helped ease pressure from the long-busy Plano and Frisco warehouses.
Community Response
Reviews have settled into the familiar Costco pattern: strong value, friendly service, and weekend congestion. Customers praise the store’s layout and cleanliness, noting that staff keep operations smooth even during rush hours. Google Maps currently shows a rating of about 4.4 stars, based on several hundred reviews since the grand opening.
Location and Area Growth
Set between Allen and McKinney, the store sits amid one of North Texas’s most active development corridors. Surrounding roads and shopping centers continue to expand, reinforcing Costco’s decision to open here. What was once an empty parcel is now a retail anchor for a growing suburban hub.
Evolution of the Area:
The intersection of Stacy Road and Highway 121 has seen an increase in development over the past 10 years. What was once largely farmland is slowly evolving into a commercial hub. The new Costco will accelerate this transformation with convenient one-stop bulk shopping for everything from groceries to electronics, home goods, and more.
