14 Best Kirkland Signature Products That Are Worth Your Money

Top picks from one of America’s favorite private labels.



Home to free food samples and some of the lowest grocery prices around, Costco just keeps getting better and better. No, seriously—according to the American Consumer Satisfaction Index, Costco’s satisfaction benchmarks are on an upwards trajectory. So, why do Americans love Costco so much? Maybe it’s the ability to buy groceries in bulk and reap the savings. Perhaps it’s the access you get to tons of unexpected membership benefits, like discounts on gas, travel, and tires. Or, it could be that Costco hasn’t raised its membership dues since 2017. 

In our book, one of the most compelling reasons to sign up for a Costco membership is the ability to shop Kirkland Signature products, the warehouse’s famous private label. In addition to offering name-brand goods at bulk prices, Costco has its own in-house brand—which usually signals even more savings to be had. But Kirkland Signature isn’t just popular because of the affordable deals. It’s considered a premium in-house brand, with more than 350 products at a high-quality caliber. And if sales are an indicator of success, the brand alone brings in a whopping $58 billion annually. Keep reading for a list of the best Kirkland Signature products to pick up on your next Costco run.

Kirkland Signature Liquid Egg Whites

Eggs are a household staple for breakfast and baking, but with the unstable price of eggs, you may find yourself buying a case of liquid egg whites to save some money. And if you do, Costco has the best prices on liquid egg whites. You can get approximately 60 servings of liquid egg whites for less than the price of two dozen whole eggs. They’re also cage-free and cholesterol-free, so they’re a heart healthy choice.

Kirkland Signature Creamy Almond Butter

Peanut is the go-to nut butter for packing sandwiches, but almond butter is a delicious and potentially more nutritious alternative. However, almond butter can be pricey—that is, if you’re not buying it from Costco. The 27-ounce jar of almond butter is one of the best Kirkland Signature products for the simple fact that it’s made exclusively from roasted almonds. It’s hard to find almond butter free from added sugar, salt, and oil, but Costco has managed the impossible.

Kirkland Signature Imported Basil Pesto

You can make your own pesto, but if you have a Costco near you, you don’t have to. Costco’s pesto is made with basil imported from Italy, which makes all the difference. It comes in a 22-ounce jar, but it tastes fresh. It’s a versatile ingredient you can add to pasta, sauces, and sandwiches, but if you can’t use it up in time, transfer it to an ice cube tray and freeze it for later.

Kirkland Signature Non-Drowsy AllerClear Antihistamine

We know that the best Kirkland Signature products save you money, but did you know that one product could save you up to 94 percent? Costco’s non-drowsy antihistamine allergy tablets last a whole year, contain the same active ingredient as Claritin, and cost just $0.02 per tablet. Claritin, on the other hand, costs about $0.36 per tablet and lasts you less than three months. There’s no prescription needed for this item, and it’s FSA eligible.

Kirkland Signature Organic Greek Nonfat Yogurt

Greek yogurt can be an affordable source of protein, and it’s linked to tons of health benefits. While all Greek yogurt varieties taste pretty much the same, there’s a few reasons why you should buy Kirkland’s Greek yogurt over other brands—it’s nonfat, sugar-free, unflavored, and packs in 18 grams of protein per serving. The 3-pound tub has enough to feed a whole family, but yogurt only lasts for about two weeks in the refrigerator, so be sure you can use it all before your time’s up.

Kirkland Signature Ultra Clean HE Liquid Laundry Detergent

It’s one thing to get your groceries from Costco, but the ultimate life hack is to get your home and cleaning essentials, too. Laundry detergent isn’t cheap, but it is at Costco. Kirkland’s laundry detergent is a high-efficiency formula, so it’s compatible with HE washing machines. If you have a front-loading washing machine and you aren’t using an HE laundry detergent, you might be leaving soap residue on your clothes and using up more water during the rinse cycle.

Kirkland Signature Alkaline AA Batteries

Is it just us, or do you always seem to need batteries when you’re freshly out? Buying batteries in bulk seems odd until you realize how often you need them. AA batteries are the most common type, and of course, Kirkland makes them. The private label also manufactures AAA batteries. Both come in a pack of 48 and have a 12-year shelf life.

Kirkland Signature Walnut Halves

Ask around, and seasoned Costco shoppers will tell you that the warehouse’s selection of nuts are among the best Kirkland Signature products. Nuts are an excellent source of healthy fats and protein, but for something so small, they can be pricey. Enter Kirkland’s walnuts—a glorious 3-pound bag of plain raw walnut halves for under $10. It’s unheard of anywhere else.

Kirkland Signature, Extra Virgin Italian Olive Oil

You may have heard that there’s an olive shortage, and you’d be correct. In fact, you can’t always be sure that the “olive oil” you’re buying is, in fact, pure or authentic olive oil. With Kirkland olive oil, you can rest easy. Check the label and you’ll notice that it’s certified by the Bureau Veritas, an agency that tests, inspects, and certifies products. This is an example of a Kirkland product that admittedly isn’t the cheapest option. You might actually spend a couple bucks more on this olive oil, but it’s worth it if you’re looking for a high-quality, Italian olive oil.

Kirkland Signature 100% Colombian Coffee, Dark Roast

There are two types of coffee drinkers in this world—the kind who are looking for a quick jolt of caffeine, and the self-proclaimed coffee snobs (their words, not ours). If you’re in the first camp, Kirkland Signature’s coffee is pre-ground, darkly roasted, and 100 percent Colombian. It’s also noticeably cheaper per ounce than what you’ll find at the supermarket. (And if the idea of buying pre-ground coffee makes you cringe because it’s not the freshest, they have whole beans too.)

Kirkland Signature French Vodka

Fun fact: You don’t need a Costco membership to purchase alcohol at the big-box store. Anyone can waltz in and buy the Kirkland Signature French Vodka straight off the shelf, and here’s why you’ll want to. It’s super smooth, easy to drink or mix in cocktails, and has long been compared to the steeply priced Grey Goose. The cons? It comes in a really tall bottle, so good luck storing that bad boy. It’s also a bit pricier than Kirkland’s American vodka, which is a better value but not nearly as smooth.

Kirkland Signature Paper Towels

There are some products you shouldn’t buy at Costco, such as the private label’s toilet paper. But that doesn’t mean you should avoid all Kirkland Signature paper products. In fact, the paper towels are one of the best products at Costco. They come in a pack of 12, and the two-ply rolls are huge. They’re a good deal—maybe not the best deal—but for the durability, they’re a winner.

Kirkland Signature Italian Parmigiano Reggiano

Cheese board, anyone? Costco carries an impressive array of cheeses, including feta, Brie, goat cheese, Manchego, and more. The best cheese to buy at Costco, however, is less adventurous but reliable—the Kirkland Signature Italian Parmigiano Reggiano. It comes in a block you can grate yourself, but there’s also a pre-shredded version sold in a tub. Grate it onto pasta or tear off pieces to snack on.

Kirkland Signature, Albacore Solid White Tuna in Water

We know canned tuna is good for us, but it’s not always the most appetizing. Canned tuna skeptics will tell you—Kirkland Signature’s canned tuna just does it differently. It’s wild-caught, packed in water, and made with simple ingredients. It’s also ridiculously high in protein at 42 grams per can, and rings up at less than $2.60 per can. We don’t know how Costco does it, but we hope they don’t stop.
