Fall is an exciting time of year to be a shopper. At stores like Costco, you'll see fully stocked shelves with seasonal pumpkin-flavored must-haves, sweet trick-or-treat essentials, and just plain warm and comforting treats. Following Costco's best new items in September 2026 are even more can't-skip picks for October 2026. We've rounded up eight products in line with this month's spooky and chilly theme, which might even add a touch of coziness to your kitchen.

As a general note, items from the same-day delivery side of Costco's website would evidently be more expensive than what you might find in store, as there's a delivery upcharge to be considered. Prices might also vary depending on what region you shop in. That said, you'll still enjoy the products the same way as the rest. Additionally, some limited-time offerings included here started rolling out in stores in September, though they weren't yet given a proper spotlight — because they're still perfect for the season, you might find them worth adding to your Costco cart. 

Miss Jones Organic Pumpkin Bread and Muffin Mix makes baking cozy treats easier this October. The simple, six-ingredient mix calls out with its homemade-like appeal. Instructions on how to make it are already included on the packaging, though adjusting your oven temperature for better box mix muffins by pushing the preheat temperature to 425 degrees Fahrenheit wouldn't be so bad, either. For an effortless upgrade, try adding chocolate chips or orange zest to the mix.  

Purchase the Miss Jones Organic Pumpkin Bread and Muffin Mix for $10.20. 

Whether you're going trick-or-treating or just want lots of sweets on hand this month, the Ferrero Assorted Candy pack from Costco is a fresh October find that gives you plenty of classic options. Each pack comes with three Trolli Sour Bite Crawlers Minis, three Nerdy Gummy Clusters pouches, seven Crunch bars, six Kinder Buenos, and eight Butterfingers.

Purchase the Ferrero Assorted Candy Variety Pack for $29.99.

There's something about the month of October that makes you want to curl up on the sofa and eat popcorn while watching the spookiest flicks you can find. Complement your cozy snacking with a popcorn popper that comes in either a subtle cream hue or a pop of canary yellow. You can even use it on any stovetop — including induction.

Purchase the GreenPan 5.39 qt. Stainless Steel Popcorn Popper for $57.99.

This new variety pack from popular brand Ghost was released at Costco at the end of September, but it's still earned itself a spotlight for this month. The Ghost Energy Drink Variety Pack is perfect for fans of the brand, as it comes with 18 cans, which are divided equally among three flavors: Strawbango, Welch's Grape-Cran, and Blue Raspberry. (The Strawbango, however, is a controversial addition because some folks dislike the flavor.)

Purchase the Ghost Energy Drink Variety Pack for $32.79.

The Nuovo Pasta Pumpkin & Bats Ravioli makes for an easy dinner. Don't worry, no actual bats were harmed here, though you can expect pumpkin- and bat-shaped pasta filled with ricotta, mozzarella, Parmesan, and aged Asiago cheese. Here's a tip for working with store-bought ravioli: If you plan to heat them in the oven, you can wrap them in a foil packet if you don't want the hassle of cleaning up afterward.

Purchase the Nuovo Pasta Pumpkin & Bats Ravioli for $10.88.

The classic Toblerone brand has a new look with this product, which features another crowd favorite: Biscoff. If you try this sweet treat that was launched in the last few weeks of September, you can expect a satisfying crunch from the Biscoff bits along with the familiar milk chocolate flavor of Toblerone. But unlike the iconic shape that we associate with the candy bar (think rows of triangles forming one long block), this one comes with 57 pieces of chocolate wrapped individually.

Purchase the Biscoff Toblerone Truffles Milk Chocolate for $13.61.

Olde Thompson Saigon Cinnamon Sticks might be the companion that you're looking for in your baked goods, hot teas, and even as a comforting fragrance in the kitchen. It's said to have a bold taste and a more aroma. (Pro tip: this is especially handy if you've just cooked fish and you want to eliminate its odor.)

Purchase the Olde Thompson Saigon Cinnamon Sticks for $6.99.

Starbucks Strawberry Acai Refreshers Concentrate is a sweet pink drink mix that offers a refreshing fruity sip. To enjoy it, add equal parts concentrate and any liquid you'd like to pair it with. You can make a strawberry acai latte with a milk addition or invent a tasty cocktail for your next brunch hangout. It invites plenty of room for play, as there could be hundreds of potential recipes you can create with just this bottle.

Purchase the Starbucks Strawberry Acai Refreshers Concentrate for $7.93.
