I am selling my iMac 27 (Late 2013) that is almost a year old on eBay. A potential buyer wanted to know if it was still possible to buy extended Apple Care on it and that is possible until December 9th. My auction ends in 2 days on December 6th so it would be unlikely for the buyer to be able to receive it in time to get the Serial Number in time. Would it be dangerous for me to remove the iMac from my Support Profile and send the Serial number to the buyer after getting a purchase and on the day that I ship it? Would it be fine since I put "no refunds" on my auction? I want to do what I can for the buyer but I also of course do not want to possibly get screwed over. What would you recommend? Thank you.
