16 Costco Products That Need Kirkland Signature Versions (2026)

Costco is a treasure trove of products, but there are some gaps in its Kirkland Signature offerings that demand attention. From household staples to innovative food items, here's a list of 16 products that should have their own Kirkland Signature versions, along with a deep dive into why these additions would be a game-changer for loyal members.

Cereal

Cereal is a breakfast staple, and Costco could revolutionize the market with its own Kirkland Signature versions of classics like corn flakes, Frosted Flakes, Cinnamon Toast Crunch, and Cheerios. The warehouse store could offer a range of options, from the mundane to the unique, providing a cost-effective and high-quality alternative to popular brands. While Costco already sells some name-brand cereals, creating its own line would be a logical step, especially for those who don't care about brand names.

Black and Herbal Tea Bags and Loose-Leaf Tea

Costco should tap into the tea market with its own Kirkland Signature tea line. Offering green tea, English breakfast tea, chamomile, chai, and Earl Grey would cater to a wide range of tastes. This move would be particularly useful for tea enthusiasts looking to save money while enjoying their favorite flavors in bulk. It would also be a smart choice for businesses looking to stock their offices or kitchens with affordable yet high-quality tea options.

Ketchup

Ketchup is a popular condiment, and Costco could create its own version, even if it's just a white-labeled version of Heinz. This would provide a cost-effective alternative to popular brands while maintaining the trusted flavor and texture that consumers love. Alternatively, Costco could develop its own unique ketchup recipe, such as a no-added-sugar or jalapeño ketchup, to entice customers to try the Kirkland-specific version over a name-brand one.

Packaged Mac and Cheese

Costco already offers well-known mac and cheese options, but it should create its own packaged version. This would be a convenient and cost-effective choice for households, especially if it means saving money. The warehouse could offer a classic recipe or explore high-protein, plant-based, or gluten-free options to broaden the menu and cater to specific dietary needs.

Soda

Costco is missing out on a big opportunity by not having its own soda. The warehouse could sell cans in larger packs, big jugs, or gallons of soda, providing a convenient one-stop shop for party essentials. With other grocery stores offering their own sodas, Costco should jump on the trend and create its own unique flavor, perhaps riffing off popular brands' flavors or offering something more inventive.

Probiotic and Prebiotic Soda

Probiotic and prebiotic sodas are all the rage, and Costco should join the trend with its own Kirkland Signature version. Offering a competitive price and a range of flavors, this product would be a hit with consumers looking to save money while enjoying a delicious and healthy beverage. The warehouse could even create a unique flavor, like strawberry vanilla, to set itself apart from the competition.

Tortillas

Costco should sell its own version of tortillas, whether it crafts its own recipe or white-labels another brand. Offering corn or flour tortillas, or even something unique like almond-flour tortillas, would be a cost-effective and convenient option for consumers. The warehouse could also incorporate low-carb or gluten-free options to cater to specific dietary needs, making Kirkland Signature tortillas a versatile and appealing choice.

Frozen Waffles

Frozen waffles are a convenient and delicious breakfast option, and Costco could create its own Kirkland Signature version. Offering classic buttermilk waffles, whole wheat waffles, or even a Belgian version, the warehouse could cater to a wide range of tastes. This would be a great addition for households looking to save money on breakfast essentials without compromising on quality.

Pancake Mix

Pancake mix is a versatile and easy-to-use household staple, and Costco should offer its own Kirkland Signature version. The warehouse could provide a classic buttermilk mix or explore protein or whole wheat options to add variety to the shelves. This would be a convenient and cost-effective choice for consumers looking to save money on breakfast essentials.

Salad Dressing

Salad dressing is a common household ingredient, and Costco should offer its own Kirkland Signature version. The warehouse could create a range of flavors, such as buttermilk ranch, to compete with popular brands like Olive Garden and Hidden Valley. This would be a convenient and affordable option for consumers looking to save money on everyday essentials.

Manuka Honey

Manuka honey is a superfood with antimicrobial properties, but it's often expensive and less approachable for consumers. Costco could change the game by offering its own Kirkland Signature jar of Manuka honey at a more affordable price point. This would make the superfood more accessible to a wider range of consumers, providing a high-quality and cost-effective alternative to popular brands.

Saltines

Saltines are a frequently used household staple, and Costco should offer its own Kirkland Signature version. The warehouse could provide a cost-effective alternative to popular brands like Nabisco, appealing to consumers looking for a budget-friendly option. This would be a great addition for households looking to save money on everyday essentials.

Canned Veggies

Costco should expand its canned vegetable offerings with its own Kirkland Signature line. Mixed veggies, canned carrots, and different cuts of green beans would be convenient and healthy options for consumers. This would be a great addition for households looking to save money on produce while enjoying the convenience of canned vegetables.

Yogurt Cups

Costco should create its own Kirkland Signature yogurt cups, offering a range of flavors and high-protein options. This would be a convenient and cost-effective choice for consumers looking to save money on breakfast essentials. The warehouse could cater to a wide range of tastes, from high-protein options to ultra-sweet and creamy varieties, making it a versatile and appealing choice.

Ready-Made Protein Shakes

Costco should offer its own Kirkland Signature ready-made protein shakes, providing a cost-effective alternative to popular brands. The warehouse could stick with classic flavors like vanilla, chocolate, and strawberry, appealing to consumers looking for a budget-friendly option. This would be a great addition for households looking to save money on protein supplements while enjoying a delicious and convenient beverage.

Juice Pouches or Boxes

Costco should create its own Kirkland Signature juice pouches or boxes, offering a range of flavors and convenient serving sizes. The warehouse could provide a cost-effective alternative to popular brands, appealing to consumers looking for a budget-friendly option. This would be a great addition for households looking to save money on juice essentials while enjoying a high-quality and affordable product.
