Sam's Club and Costco have a similar number of club locations across the U.S. However, Costco generates almost twice the annual revenue compared to Sam's Club. Both warehouse retailers require club memberships and offer their own private label brands, Member's Mark for Sam's Club and Kirkland Signature for Costco.
Kirkland Signature was launched in 1995 by Costco. The brand was created to offer better quality goods at lower prices, and it now accounts for a significant portion of Costco's annual revenue.
Sam's Club is focusing on improving its private label brand, Member's Mark, to compete with Costco's popular Kirkland Signature line3. By offering high-quality, exclusive items at competitive prices, Sam's Club aims to attract more customers and close the gap with Costco in terms of annual revenue.
