Which Kirkland Brand Products Are Worth It? Start With These

Costco’s Kirkland Signature brand consistently offers high-quality products at a lower price point than you’ll find pretty much anywhere else. The value of the Kirkland Signature brand is actually part of the reason Costco wins out over Sam’s Club for items like dog food and batteries. Some Kirkland products so closely resemble their name-brand counterparts that you can’t even tell the difference.

You might already know you can find name-brand Costco clothes at ridiculously good prices, but did you know some of the same manufacturers also make Kirkland Signature products? Companies like Starbucks and Keurig are behind the Kirkland brand coffee — so why pay more for the exact same thing?

If you’re already a Costco member (or trying to decide if a Costco membership is worth it), use this as your guide to the Kirkland Signature brand. Learn whether Kirkland Dog Food can replace the popular name brand stuff (spoiler alert: it can) and which Kirkland products not to buy.

We’ve also included a list of our favorite Kirkland brand products that offer significant savings over the name-brand version.

Is Kirkland a good brand?

The Kirkland Signature store brand, sold exclusively at Costco, is known for being high-quality.

Costco partners with reputable manufacturers to create nearly the same products as name-brand competitors. But since they sell the products in bulk, they can undercut the prices. In fact, they'll only put out a Kirkland product if it offers at least 20% value over the name brand.

Many Kirkland brand items get manufactured in the same plants as the top brands, which means the only difference is the label on the packaging.

KCL TIP: While you may find some Amazon listings for Kirkland products, don't be fooled. Third-party sellers on Amazon will often mark up the prices on Costco products to make a profit.

Who makes Kirkland Signature products? See the big name manufacturers who make Kirkland products:

We already talked about how Starbucks and Keurig make the Kirkland Signature coffee offerings, but you might not realize how many other Costco-brand items come from well-known manufacturers.

For example, you can buy Duracell Batteries at Costco — but Duracell actually creates the Kirkland Signature AA and AAA batteries, so why not opt for the Costco brand?

In some cases, the manufacturer logo appears on the packaging along with the Kirkland logo. You can see this on products like Kirkland Cranberry Juice, where the Ocean Spray brand name gets printed right on the label.

• Diamond Pet Foods: This brand produces some of the highest-quality dog food on the market, and they also produce Kirkland Signature Dog Food.

• Duracell: Kirkland Signature Batteries are made by Duracell, and you can buy a 48-pack of Kirkland AA Batteries for $15.99 (vs. a 40-count pack of Duracell AA Batteries for $20.99).

• Ocean Spray: Whether you buy Craisins or bottled cranberry juice, consider that many of the Kirkland Signature versions are made or bottled by Ocean Spray.

• Reynolds: Never buy name-brand aluminum foil or plastic wrap again. Both Kirkland Signature and Reynolds’ logos are featured on the packaging — at a lower price point than Reynolds Wrap.

• Starbucks: The Kirkland Signature Espresso Blend Coffee or Regular House Coffee gets made by Starbucks, but with a much easier-on-the-wallet price tag.

Best Kirkland Brand Deals at Costco

Prices quoted below were accurate as of March 2025 at my local Costco store in Central Florida, but know that prices may vary depending on your location.

1. Kirkland Signature Purified Water 

You can buy 40 bottles of Zephyrhills Bottled Water at Costco for $6.49, which comes out to $0.16 per bottle. Or get the exact same number of Kirkland Bottled Water for $3.99, which is $0.10 per bottle.

That means you’ll save $0.06 per bottle when you buy Kirkland Bottled Water instead of Zephyrhills. And we dare you to blind-taste test them to tell the difference.

2. Kirkland Signature Diapers

If you have kids in diapers, think twice before you shop a name brand. Kimberly-Clark (the same company that manufactures Huggies) used to make Kirkland brand diapers. But as of March 2025, Costco switched the manufacturer of their Kirkland Signature diapers to First Quality, the manufacturer of Cuties brand diapers.

"This quarter, we worked with a new supplier to rework our Kirkland Signature diapers," said Costco CFO Gary Millerchip on the Q2 2025 company earnings call. "Improvements versus the prior offering include a longer and thicker absorbent layer, softer outer cover, and two times more stretch in the waistband. As well as improving the quality of this item," he added, "we were able to increase the value by 11%."

With the new Kirkland diapers, you'll save 22% - 30% over the name brand.

Price of Kirkland Diapers vs. Huggies

3. Kirkland Signature Hard Seltzer 

Kirkland Hard Seltzer tastes just like White Claw Seltzer but for $0.24 less per can.

You can pick up a 24-pack of 12-ounce Kirkland Hard Seltzer cans for $23.99 at Costco ($1 per can), or a 24-pack of 12-ounce White Claw cans for $29.85 ($1.24 per can).

4. Kirkland Signature Bath Tissue 

Kirkland Toilet Paper is a household staple, especially when you compare the price to the Charmin pack sitting right next to it. The Kirkland pack of 30 rolls (1,425 total square feet) costs $20.99, which comes out to just $0.01 per square foot. Compare that to the Charmin pack, which costs $30.89 for 835 square feet, or $0.04 per square foot.

You’ll save $0.03 per square foot when you choose Kirkland over Charmin, which can really add up when you’re talking about a lifetime of purchasing toilet paper for your family.

5. Kirkland Signature Organic Coconut Water

Buy Kirkland Organic Coconut Water instead of Vita and pocket $0.24 savings per bottle. They taste so similar that you might not even notice switching one out for the other. But your wallet will definitely notice the difference.

At Costco, the Kirkland Signature Coconut Water costs $10.49 for a 12-pack of 11.1-ounce bottles, so you're paying $0.87 per bottle. Vita Coconut Water is priced at $19.99 for an 18-pack of 11.1-ounce bottles, which is $1.11 per bottle.

6. Kirkland Signature Napkins

When it comes to stocking your kitchen with everyday napkins, Costco’s Kirkland Napkins are a steal at $11.89 for a 1,120-count pack ($0.01 per napkin). Especially when you compare that to the price of Vanity Fair Napkins at Costco, coming in at $11.99 for a 660-count package ($0.02 per napkin). You’ll get nearly twice as many Kirkland napkins for the same cost.

7. Kirkland Signature 12-Piece Hard-Anodized Cookware Set

When it comes to great non-stick cookware, Kirkland’s 12-piece set for $129.99 is cheaper than Ninja’s 12-piece cookware set which you can buy on Costco.com. Either set will cook you a great dinner, but the Kirkland option will save you $70.

8. Kirkland Signature Flushable Wipes

When you opt for the Kirkland Flushable Wipes instead of Cottonelle, you’ll save $0.01 per wipe. You'll pay $14.99 for a 640-count pack ($0.02 per wipe) versus $16.49 for a 560-count of the Cottonelle version ($0.03 per wipe). That $0.01 less per wipe can add up if you go through a lot of these per year.

9. Kirkland Signature Ultra Shine Dishwasher Pods

If you want to spend $0.11 less per load of dishes, then you’ll want to ditch Cascade Dishwasher Pacs in favor of Kirkland Dishwasher Pacs. You’ll get the same clean dishes for half the cost per load, as the Kirkland pacs are $0.10 each ($11.99 for a 115-count container) versus the Cascade Complete pacs which are $0.20 each ($18.49 for a 93-count container).

10. Kirkland Signature Laundry Detergent 

Costco’s Kirkland Laundry Detergent Free & Clear promises 146 loads for $17.99, while the All Free & Clear bottle at Costco offers 158 loads for $19.89. That equals around $0.01 savings per load when you buy Kirkland over All. And if your house is anything like mine, those savings can really add up over time.

11. Kirkland Signature Premium Paper Towels

When calculating the cost per square foot of paper towels, Kirkland products are a steal compared to Bounty Paper Towels sold by Costco.

You’ll get a 12-pack of paper towels with either brand, but the Kirkland Paper Towels have 1,026 total square feet per package for $19.99, while the Bounty Paper Towels at Costco only have 656 total square feet for $24.99. That makes the price per square foot half the cost when you go with Kirkland, saving you $0.02 per square foot.

Skip These Kirkland Brand Items

While we generally love everything in the Kirkland Signature brand, there are a few items that aren’t as good of a deal. These are the Costco-brand products we recommend skipping.

Kirkland Signature Spices

You can buy spices like ground cinnamon and garlic powder in bulk under the Kirkland Signature brand, but unless you’re a chef or need to cook for a large family, we recommend skipping the bulk spices.

That’s because spices typically expire after two years, and the money you save by buying the supersized bottle doesn’t do you any good if you can’t actually use the product before it goes bad. The same goes for bulk baking supplies like flour and sugar.

KCL TIP: Always check the shelf life of bulk items before you splurge on a large quantity.

Kirkland Signature Milk 

There’s nothing technically wrong with Costco’s brand of milk, other than the fact that it’s sold in such large quantities. (Just make sure you can use it all before it goes bad.)

But one thing that Costco shoppers comment on repeatedly is how much they dislike the shape of the milk jugs. Costco’s milk products come in square jugs, which several Reddit users say makes it prone to spilling — meaning you could waste more than you save.

Kirkland Signature Facial Tissues 

Most Kirkland paper products are totally worth it (their toilet paper, paper towels, and napkins all made the list above), but we just don’t love their facial tissues as much as the rest of the items.

Kirkland Signature Facial Tissues cost $16.49 for 1,008 tissues (that's $0.016 per tissue, if we really get into the math), while a pack of Kleenex Ultra Soft at Costco is $21.39 for 1,020 tissues (that's $0.021 per tissue). But rounding up, they're both about $0.02 per tissue — and the Kleenex boxes go on sale for $5 off about every 2 - 3 months. So you can get the name brand facial tissues for less pretty often.
