30 Best Kirkland Products You Should Buy at Costco

Many of warehouse club Costco's store-branded Kirkland Signature items get high marks for quality and value.

If you’re of the notion that store brands are a notch below national brands, Costco’s out to change your mind. The warehouse giant uses its huge market share to strong-arm suppliers to put quality as well as value into Costco’s proprietary brand Kirkland Signature offerings. More than a quarter of Costco’s annual sales reportedly come from its Kirkland product lines, which first hit store shelves in 1995.

Those products helped pad Costco’s net income of more than $1 billion in 2021 from more than 111 million members shopping at 828 stores worldwide – and spending $60 to $120 (for now) for annual memberships (we expect that Costco will follow Amazon Prime in raising the cost of membership).

Costco has continually expanded its array of Kirkland Signature products, with the distinctive black, red and white design, currently numbering more than 350 individual items, from batteries and bacon to maple syrup and motor oil. Many, if not all, are manufactured by top national and regional companies, including Duracell, which makes Kirkland Signature batteries, one of our recommendations. The Kirkland Signature products are often found next to the national brands on Costco’s shelves, with the Kirkland products 20% less.

On some Kirkland Signature products, don’t be surprised to see the name-brand manufacturer’s name co-branded with the Kirkland Signature, including Stearns & Foster on a Kirkland Signature by Stearns and Foster mattress (starting at $1,049.99), nationally known Ocean Spray on the Kirkland Signature Cranberry Premium juice, and aluminum foil giant Reynolds on boxes of Kirkland Signature aluminum foil. Oh, and the name? It comes from the city in Washington state where the company is headquartered.
