Costco sells out of Adidas backpacks in hours

Costco shoppers are snapping up Adidas backpacks, Halloween throw pillows and Kitty City catios, according to a 21-year Costco employee who shared her favorite finds on shelves right now.

The veteran worker says the mix reflects Costco’s signature blend of brand-name basics, holiday tie-ins and pet-friendly upgrades—all priced to move fast. Adidas backpacks are selling out within hours, she reports, while Halloween items are arriving earlier each year as Costco leans into seasonal sales. The catio, a screened porch for cats, is a newer addition that’s gaining traction as pet owners look for safe outdoor access without leashes.

Prices are still low for the volume. Adidas backpacks run about $25, pillows are $12.99 each, and the Kitty City setup costs around $150. The employee notes Costco moves inventory quickly, so once pallets empty, the items vanish until next season. Social media buzz is helping too—shoppers post unboxing videos of the catio, driving more demand.

Longtime Costco watchers say this cycle isn’t new, but it’s accelerating. The retailer has always bet on rotating curated goods at low margins to pull in crowds. Now, with online competition heating up, Costco is doubling down on seasonal “treasure hunt” items that can’t be found anywhere else. Expect more brand collabs and pet products to hit floors ahead of the holidays, with the same fast sell-through.
