Bought a 'used' item at a discount from Warehouse Deals. Impossible to tell if it was considered "used" as it was a remanufactured item (typical of auto parts but something I did NOT want for that particular item) or just a returned item. However, I couldn't see it and it worked fine. He was also eligible for a $20 rebate on returning Delco's main AC product, so I got that too by sending the old one back. Happy with the purchase.
