Hello I'm planning on getting an Apple Watch sport, and want to get AppleCare+ for it. The problem I worried about is what if the seller doesn't have the receipt. Will I still be able to get AppleCare+? Plus since its in his/her name, will it be tied to the other persons info? What if I do get an apple watch with AppleCare+ already, do I need to transfer it to my info? I hear some people say it's tied to the devices serial number, but on Apple's website it states you need to fax, mail, or evenemail some things like a copy of the original receipt. I'm so confused! I keeping getting mixed answers what do I need to do?
