Costco Member Returns & Kirkland Overstock Loads
Costco member return loads carry warehouse club inventory where customers buy in bulk — returns tend to be higher-value items in better condition than standard retail liquidation. Costco processes liquidation through its B-Stock auction platform, with lots graded A/B (lightly used or open box) or C/D (heavier use, missing components). A resale certificate is required. Kirkland Signature products — Costco's private label — cannot be purchased new outside Costco, creating strong resale margins for eBay resellers, Amazon FBA sellers, and wholesale distributors. Kirkland categories include food, snacks, cleaning products, personal care, supplements, and household essentials. Costco snack truckloads ship 24 pallets of shelf-stable food and beverages. Grocery outlet operators, flea market food vendors, and Amazon FBA grocery sellers source these loads — verify remaining shelf life before purchasing. Costco inventory skews toward club-sized packaging, multi-packs, and higher individual item values suited for eBay, Mercari, discount store, and online marketplace resale channels.
