Company Description

Costco Wholesale Corporation operates an international chain of membership warehouses, mainly under the "Costco Wholesale" name, that carry quality, brand name merchandise at substantially lower prices than are typically found at conventional wholesale or retail sources. The warehouses are designed to help small-to-medium-sized businesses reduce costs in purchasing for resale and for everyday business use. Individuals may also purchase for their personal needs. Costco's warehouses present one of the largest and most exclusive product category selections to be found under a single roof. Categories include groceries, candy, appliances, television and media, automotive supplies, tires, toys, hardware, sporting goods, jewelry, watches, cameras, books, housewares, apparel, health and beauty aids, tobacco, furniture, office supplies and office equipment. Costco is known for carrying top quality national and regional brands, with 100% satisfaction guaranteed, at prices consistently below traditional wholesale or retail outlets.
