So I ordered my 5K retina on 29/11. Was dispatched on 01/12 and arrived on 05/12. I purchased AppleCare at the same time. It appears my AppleCare expires on 30/11/17. Should it not actually expire on the anniversary of when I received my iMac (05/12/17) I know it's only 5 days, but 5 days is 5 days. Thanks.
