How does this strange partnership work exactly? I sent a vintage restored computer to the amazon warehouse so they can sell it for me and I used UPS (partnered carrier) to ship it. It was lost in transit. Amazon compensated me for my loss. However, I'm left sad because I spent a month restoring the computer and I would have liked a customer to end up with it so they can appreciate the beauty. Is there any effort at all made to locate my item? When I complained to amazon they compensated me within 9 minutes. Didn't seem like any investigation took place.
