20 Kirkland Products Secretly Made by Famous Brands

That cheap Kirkland label at Costco is hiding some of the most famous brands in the country. The batteries are Duracell. The tuna is Bumble Bee. And on twenty products, the store brand is either the name brand in disguise or it beats the name brand outright in independent testing, for a fraction of the price. We traced who actually manufactures Kirkland Signature and ranked the 20 Costco products genuinely worth buying, food, drink, and the household and health staples you re-buy every month, from the sparkling water and protein bars to the bacon, the batteries, the rotisserie chicken, and the coffee that spent years labeled Custom Roasted by Starbucks. Every pick is backed by documented evidence: Consumer Reports and ConsumerLab tests, UC Davis olive-oil verification, USP Verification, and Dog Food Advisor ratings.
