Costco Wholesale is a members-only warehouse selling a huge variety of items. This location is a nice place with a good selection and is less busy than other nearby Costcos, though weekends can be really busy and hectic. The store is always clean and is setup great for moving throughout the warehouse. Staff are nice, friendly, and very helpful. It offers plenty of choices, including a local specialty of wine bottles from various Woodinville wineries. However, the groceries and produce are getting a bit more pricey. The gas line is typically not too long.
