Most people familiar with Costco know about the retailer's treasure hunt philosophy. The chain intentionally creates an environment that encourages shoppers to stumble upon new items while buying grocery staples and household goods. Costco also introduces new items to its core inventory on a regular basis in an effort to keep customers on their toes (and keep their wallets open). With autumn in full swing and Halloween right around the corner, we checked out Costco's October arrivals and curated the top picks for your viewing pleasure. 

This month, shoppers will find wholesome snacks for little tykes, practical kitchen items, and lots of sweet treats. We also included some seasonal goods, including a spooky energy drink flavor and a dip inspired by a beloved campfire food. Available product links and prices have been added for each item, but remember that you can't always find the same products at every Costco. In an effort to meet the needs of specific neighborhoods and regions, the chain may offer different inventory at different locations.

The intention behind the donut-shaped design of these baked treats isn't just to mimic a tractor wheel. Their easy-to-clutch shape is perfect for both toddlers and older children. And with wholesome ingredients like sweet potato, apple, spinach, and pumpkin, parents can feel good about what their kids are snacking on.
