There was a seller on eBay selling a 2015 MacBook Pro as new, sealed in the box. He had the serial number showing on the box and the box was sealed in its plastic. When I ran the serial number everything checked out, but it says its AppleCare protection plan was up in Oct. 2019. Can it really be listed as brand new never been used if that is the case? Just curious as something didn't add up to me. Thanks!
