Costco Wholesale is a members-only warehouse selling a huge variety of items including bulk groceries, electronics, and more. Many customers find it the best grocery store, with everything being affordable, including gas and organic products. The business is known for having great deals, which keeps members coming back for personal and business needs. The staff are frequently described as super friendly, helpful, courteous, kind, and amazing, with some customers referring to them as a loving family. They treat everyone equally and are noted for taking care of their own employees. However, the store is very busy all the time, and some find it unpleasant on weekends. Parking can be a bit challenging at some locations, though using a covered parking garage is a suggested solution. Most reviews are positive, though there can be occasional negative interactions with staff, which customers hope are isolated bad days. One specific frustration noted is that at some locations, you cannot simply walk in and order a ready pizza; instead, you must call ahead. Overall, the service is viewed positively, and the store earns significant respect and loyalty from its members, with some stating they will only shop there.
