9 Costco Must-Haves To Look For In October 2026

We may receive a commission on purchases made from links.

If you're a new Costco shopper, there are a few must-try food items you need to get on your first shopping trip. But if you're not a Costco novice, you already know about all the essentials — which means you're probably much more interested in the new items that have made their way to Costco's shelves. Anyone who falls into the latter group must look out for these while shopping at the retailer in October 2026.

This list of must-haves includes new snacks for you to enjoy, fun beverages for an afternoon pick-me-up, and delicious sweet treats from the bakery section. These new items are all everyday products that we hope stick around for the foreseeable future, rather than seasonal items that fit the autumnal theme (and if you're looking more for that, you can read about the pumpkin finds to look for at Costco this fall). Read on to see what's new at Costco this month — and just keep in mind that we'll be listing the online prices, which may differ from the prices in-store.

First up, we have one of the yummy new snacks: Kirkland Signature rice crackers. There are a variety of flavored rice crackers in this bag: wasabi crescents, sesame teriyaki mochi, miso nori rounds, sesame half moons, chili mochi, soy crescents, soy nori mochi, soy sticks, and sweet & sour twists. Keep a bag of these around to snack on or serve them as a pre-dinner snack at a Japanese-themed dinner party.

Buy a 32-ounce bag of Kirkland Signature rice crackers from Costco for $12.49.

Kirkland has its own flavored sparkling water now — and there are three delicious flavors in the pack. Black raspberry, orange mango, and kiwi strawberry sparkling water bottles are naturally flavored, contain B vitamins, and have just five calories per bottle with zero grams of sugar. The pack has eight bottles of each flavor, so it should be able to satisfy your bubbly drink craving for a while (before you need to buy a new pack).

It's always a good idea to have a jar of strawberry spread around. There are so many ways to use up this pantry staple — spread it on toast, integrate it into a homemade dessert, or make a tried-and-true PB&J. This organic strawberry spread from Costco contains just four ingredients: organic strawberries, cane sugar, fruit pectin, and citric acid. It has 40 calories and nine grams of sugar per one-tablespoon serving.

If you're looking for a new coffee roast to try, check out the new Kirkland organic Mexico Oaxaca whole-bean coffee. It's a medium roast with notes of caramel, chocolate, and roasted peanuts. You can use this bag to make coffee however you please, but if you want an idea, there are instructions for Kirkland's brewing suggestion right on the bag.

Sweet treat lovers will want to be on the lookout for these new Kirkland caramel s'mores clusters. Each cluster includes kettle-cooked caramel, graham cracker pieces, and marshmallows, all wrapped up in sweet milk chocolate. You can expect these to have all the tastiness of a regular s'more — plus the addition of caramel — but in a less messy form. If you don't have the time or ingredients to make classic s'mores, you can simply reach for this bag instead.

Buy a two-pack of the 26-ounce bags of Kirkland Signature caramel s'mores clusters from Costco for $44.99.

Nuts always make for a great snack — after all, they're filling, tasty, and offer a bit of a protein boost. This variety pack from Kirkland is perfect because it already comes with individually sized bags and you have three varieties to choose from. The bag comes with seven bags each of pistachios, cashews, or mixed nuts (cashews, almonds, pecans, and macadamia nuts). All are roasted and salted, so there's plenty of flavor.

If you're looking to add some electrolytes to your diet, then you should add these Kirkland Signature hydration sticks to your Costco cart. All you have to do is mix one stick — either lemon lime or strawberry watermelon — with 16 ounces of water and you're good to go. Each stick contains 500 milligrams of sodium, 40 milligrams of magnesium, 400 milligrams of potassium, and 640 milligrams of chloride. It's also low-calorie and sugar-free.

Next up, we have a delectable bakery item: the butter cinnamon sugar loaf. It's a butter pound cake loaf with a cinnamon swirl and a cinnamon-and-sugar top coating. Try a slice of this delicious loaf warmed up with extra butter or a scoop of vanilla ice cream on the side for an even more decadent dessert. It will also taste great straight from the box, without any extra prep, and can be enjoyed in the morning with your favorite coffee.

Buy the Kirkland Signature butter cinnamon sugar loaf from Costco for $11.34.

Finally, we have one more bakery item: the Kirkland Signature cherry almond cake. This is a relatively new item, but it has already made our list of the best Costco cakes of 2026 (so far), so you'll definitely want to grab one. It has a tart cherry filling and an almond streusel topping, along with plenty of donut sugar on top. So, it's fruity, nutty, buttery, and plenty sweet.
