Why Costco Went All in on Kirkland — and How It Paid Off

SEATTLE — In a bold move that defied industry norms, Costco introduced its private label brand, Kirkland Signature, over 30 years ago. Today, the brand accounts for approximately one-third of the company's sales, with over 350 products across various categories. The decision to create a single private label brand was a risk, as most successful retailers at the time used multiple brands divided by product type.

However, Costco's approach has paid off, with Kirkland Signature becoming a negotiation tool that has forever changed the big-box retail landscape. The brand's success is largely due to Costco's limited selection approach, carrying only 4,000 items compared to the 140,000 items carried by other retailers. This strategy allows the company to focus on high-quality products and maintain a strict maximum markup of 14%, giving it a competitive edge.

The introduction of Kirkland Signature was a result of Costco co-founder Jim Sinegal's observation of the rising prices of name-brand items, despite decreasing manufacturing costs. Sinegal saw an opportunity to create a private label brand that could offer high-quality products at lower prices. The company initially used multiple private label brands, but eventually consolidated them under the Kirkland Signature name, a decision that went against industry best practices.

The Kirkland Signature brand has become a driving force behind Costco's sales, with suppliers competing to offer the best prices and products. The company's limited SKU environment, where only a few products are carried in each category, creates a competitive environment for suppliers, with the introduction of a new Kirkland Signature item often leading to a reduction in sales or even the removal of a national brand from the shelves.

As one industry expert noted, "Kirkland Signature is seen as a shining example of what a retailer can do with its house brand." The brand's success has also led to it becoming a significant negotiation tool, with suppliers eager to avoid being priced out of the market by Kirkland Signature products.

In recent years, sales of private label brands like Kirkland Signature have grown at a rate four times faster than national brands, with Kirkland Signature alone generating $80 billion in sales. While analysts say that replicating Kirkland's success will be challenging for other retailers, the brand's impact on the retail industry is undeniable. As one Costco executive noted, "It's an $80 billion brand, so it drives a lot of sales. Nobody wants to be that dramatically higher price than them."

As the retail landscape continues to evolve, one thing is clear: private label brands are playing an increasingly important role in driving sales and customer loyalty. For Costco and Sam's Club, their strategic approach to private labeling has paid off, with Kirkland Signature and Member's Mark becoming household names. Despite this success, other big retailers have been slow to follow suit, opting instead to maintain multiple private label brands.

However, as the numbers show, the club channel model is winning in the private label food and beverage space. With Costco's Kirkland Signature sales on the rise and Sam's Club's private label sales nearly doubling since consolidation, it's clear that this approach is yielding results. As Costco's CEO continues to personally oversee the development of new Kirkland products, it's a testament to the company's commitment to quality and value.

As the retail industry looks to the future, it will be interesting to see if other companies will adopt a similar approach to private labeling. For now, it seems that Costco and Sam's Club are reaping the rewards of their strategic decision-making. With their focus on quality, value, and customer loyalty, they are setting a high standard for the industry. As the CEO's green ink meetings become a thing of the past, the legacy of this approach will undoubtedly continue to shape the retail landscape for years to come. In the end, it's clear that the private label revolution is here to stay, and Costco and Sam's Club are leading the charge.
