This Is One of Costco's Biggest Secrets

There may be something familiar about the warehouse's beloved brand, Kirkland Signature.

If you shop at Costco, then the brand Kirkland Signature is probably extremely familiar to you. 

The warehouse's beloved in-store brand is a staple that allows people to buy the generic version of a product for way less. As of 2017, according to The Wall Street Journal, about a quarter of Costco's $118.7 billion in annual sales came from Kirkland Signature products—and that percentage continues to grow.

And as customers rave, the generic products are of good quality and value. So what's the big secret behind Costco's adored brand? According to Money Talks News, many of Kirkland Signature products sold at Costco are actually made by the same major brands you know and love by name. Yep, from Starbucks to Jelly Belly, these household names are making Costco's generic offerings.

Here are some of the companies that Costco works with to maintain its widely successful Kirkland Signature brand. And for more Costco news, check out the 6 Things You'll See at Costco This Year.
