October 2026: Hot Costco Items You Won't Want To Miss

We may receive a commission on purchases made from links.

It feels like we have barely had a chance to draw breath after running down the September 2026 goodies on offer in Costco (never mind eat through them all), but here we are again, poised to reveal the latest must-haves ready at the warehouse store. As the pumpkin-themed panoply of last month disappears, we get the impression Costco is turning its attention to the colder, darker months, bringing a bit of a self-care vibe to October's crop of new items.

Amid some gorgeous-looking and delicious-sounding sweet treats, there's a bumper pack of the ultimate winter soup (start stocking up on lemons for a soup upgrade hack), as well as colorful, fruity wellness shots and a tub of flavorsome salt crystals that come all the way from the coast of Cornwall. As always, all pricing and availability details were correct at the time of writing, but if there's a particular item or two you really want, drop your local Costco a line to ensure it's in stock. Everybody ready? Let's dive in!

You can be the trick-or-treat hero of your street on Halloween by offering full-size Butterfinger, Crunch, and Kinder Bueno bars from this brand new, bumper box of Ferrero goodies to any and all comers. The box also contains six shareable pouches (including mini Trolli Sour Brite Crawlers), so you can delight the fam during movie night or keep some all to yourself for a moment of sweet indulgence.

The latest addition to Costco's fresh fish line is currently only available online, but, wowsers, it's well worth firing up the laptop. Sustainably raised without antibiotics in the waters of Argentina and Peru, this steelhead trout comes with skin but no bones. You get between 5 and 7 ounces of fish for your money (that works out to 23-29 portions), and if you've never cooked trout before, we've got you covered.

Buy Steelhead trout for $199.99.

Hands up: who's already yearning for the long, hot days of summer? This zingy punch is a burst of fruity brightness with every sip that brings to mind seasons just passed. We like the sound of the orange-strawberry combination, and as well as keeping us hydrated (it's easy to let it slip as winter rolls around), half a bottle supplies 100% of our daily recommended vitamin C. Sweet!

Buy SunnyD Citrus Punch, Orange Strawberry for $13.49.

Holy moley — could this be the greatest pairing since PB met J? Biscoff's cinnamony cookies have been turned into a gooey, sweet filling, peppered with honey and almond nougat, and slipped into a rich, Swiss chocolate shell. Toblerone has still managed to make it a weird shape to eat, but we're prepared to try these truffles out, many, many times, just to make sure.

Buy Toblerone Biscoff Truffles for $13.79.

Traditionally prepared matcha tea can have more caffeine than coffee, so if you want to give it a whirl, now's your chance. Once a bit of a bougie fad but now firmly established as a consumer fave, this fine-milled matcha green tea comes from Japan and is perfect for adding to smoothies or a latte, all manner of baked goods, and of course, for making a lovely, earthy-flavored cup of tea!

The search for the cutest dessert for October 2026 might just end here with these delightful strawberry chiffon cakes from — according to the packaging — Korea's top bakery. There are 12 individually wrapped cakes in a box, making these sweets perfect for lunch boxes, picnics, or dropping into your bag for a dose of sweetness at work. At less than $7 each, we think these boxes will fly off the shelves.

Getting fruit into the family meal rotation can feel like a full-time job, especially when someone's fave fresh kind isn't available in stores. Costco can help you solve that little problem with these vegan, kosher, and organic snacks from Pure Organic. Made with the juice and purée of real fruit, each variety pack of funky jelly twists contains 12 each of the blueberry-raspberry and strawberry-mango flavors.

Buy Pure Organic Twisted Fruit Bites for $13.19.

When the weather turns chilly, we love curling our hands around a steaming bowl of chicken noodle soup, so we'll be among the Costco regulars snapping up this multipack from Campbell's which, at the time of writing, had $6 off. It's a delicious blend of antibiotic-free white chicken meat, farm-grown carrots, and egg noodles (among other ingredients), in a chicken bone broth. If you fancy supercharging this classic soup, check out a key soup tip from Emeril Lagasse.

Buy Campbell's Simply Chicken Noodle for $10.79.

These individually wrapped snacks could be as good for the planet as they are our taste buds. With no dairy, gluten, or GMO ingredients, they are also plant-based and kosher, while each bite packs a whopping 13 grams of whole grains. You get 12 each of the Stuff'd Apple Pie and Stuff'd Strawberry snacks per carton, and we bet the kids won't care about how healthy they are as they gobble them down.

Buy Bobo's Oat Bites, Variety Pack for $14.79.

If you're looking for more flavor from your dishes but still want to reduce your salt intake, these sea salt crystals harvested from Grade A Celtic waters on Britain's Cornish coast are just the thing. The company claims the sea salt's blend of natural minerals, including calcium, magnesium, and potassium, enhances flavor in addition to the sodium. We can't wait to give it a whirl over some fresh blueberries.

Buy Cornish Sea Salt Company Celtic Sea Salt Crystals for $20.93.

If you usually buy extra virgin olive oil in a glass bottle, this pack of four (currently online-only) refills from Terra Delyssa is an eco-friendly way to keep it topped up, helping cut carbon emissions by up to 60%, per the packaging's claim. There's more good news, too. Terra Delyssa's award-winning, mild-flavored EVOO from Tunisia is harvested by hand, then cold pressed, with an end result that's as culinarily flexible as it is delicious.

Buy Terra Delyssa Organic Extra Virgin Olive Oil Refill Pouches for $39.99.

These handy, fruit-based shots sit in the fridge and are a great way to give yourself a little boost, especially first thing in the morning, when it's often darker and harder to get going. Made from organic, cold-pressed juices, they provide 100% of our daily vitamin B6 and B12 needs, as well as a handy dose of caffeine extracted from organic green tea. We're more than ready to make them part of our breakfast routine.
