Costco lots carry the highest per-item values on B-Stock — appliances, furniture, and electronics that can each resell for hundreds — which makes them a local-resale play, not a ship-to-buyer one. The economics live and die on freight: an appliance or furniture pallet can cost $300–$500 to move, so buyers within delivery range of a Costco depot have a structural advantage. Furniture in particular clears fast on Facebook Marketplace and OfferUp. Watch for warehouse-handling cosmetic damage on returns, and price against live Costco.com retail to know your real spread. This is a category for resellers with a truck, storage, and the capital to absorb a heavy freight bill.
