Kirkland Signature is Costco Wholesale's store brand. The Kirkland signature name appears on approximately 20 percent of the products found in the store. Kirkland Signature was introduced 20 years ago in effort to offer Costco Wholesale members everyday purchases at affordable prices without sacrificing quality.
The brand appears on items such as clothing, cleaning supplies, food items, and health and beauty products. With Kirkland Signature, Costco specifically focuses on both quality and pricing. The brand gives Costco the opportunity to develop new products while closely controlling the quality of these specific items. In addition, the brand is a driving force in keeping the pricing of competing brands down. Costco encourages its members to compare Kirkland Signature with its brand name counterpart.
