  • Welcome to the Club! The Insider's Guide to Costco


    Costco also features a fine line of more than 300 quality products under our own private label. We have taken great care in selecting products such as housewares, luggage, pet food and bedding, baby wipes, diapers, baby formula, apparel, wine, snacks and more, which deserve to carry the Kirkland Signature™ name. All Kirkland Signature™ products are guaranteed to be of equal or better quality than name brands.
