Costco’s own Kirkland Signature store brand has been going strong since 1995 thanks to the fantastic quality and affordable prices it offers shoppers. Customers are so enamored by Costco’s name brand that a quarter of Costco’s annual sales now reportedly come via its Kirkland Signature label. Costco members love to rave about their favorite Kirkland items but are probably unaware that behind that red and black Kirkland logo lies some huge retail giants manufacturing the products.

From pizza to cheese, prosecco to laundry detergent, and motor oil to diapers, here are some of the companies you may, or may not know, are behind Costco’s own Kirkland Signature label.
