Costco Wholesale in Southlake is a members-only warehouse offering a wide selection of bulk groceries, electronics, and more at affordable prices. It is a popular choice for large families and those seeking quality products in large quantities. The store is conveniently located close to residential areas, making it easily accessible. The variety of items includes organic options, and the store generally provides fast and accurate service. However, shopping can be challenging due to crowded conditions, especially on Sundays. A significant downside is the self-checkout process, which is often frustrating and slow because it requires an employee to scan each item. Employees working at self-checkout can be rude and unhelpful, making the experience worse. Customers have noted that there used to be scanners for self-service, but these are no longer available, forcing shoppers to take items out of their carts and go to a separate scanner. Despite these issues, Costco remains a good place to shop if shoppers avoid the self-checkout lines.
