On Friday, Costco launched its first-ever Nike SB Dunk Low x Kirkland Signature sneaker in four U.S. regions—New York, Oregon, California and Washington—at an initial price of $134.99. Drawing directly from the retailer’s in-house Kirkland Signature sweatshirt palette, the sneaker combines gray sweatshirt-like uppers with pilled interior linings and prominent Kirkland emblems on the heel and tongue. Within 72 hours, resale listings on StockX, eBay and GOAT numbered over 660 pairs, trading between $400 and $1,000 and reflecting markups exceeding 200%. The collaboration also features a removable hang tag mimicking a Costco Executive Membership card and a tongue label styled after the chain’s in-store price sheets. The speed and scale of secondary-market activity underscore both Costco’s brand cachet and the growing appeal of retail-club exclusives among sneaker collectors.
