I've spoken to Apple support twice through Apple Web Chat and once on the phone, and I'm confused about AppleCare. Am I allowed to request a direct mail-in for repairs on my iMac with my complimentary support, or do I have to purchase the three-year AppleCare Protection Plan for such support features? Is there a difference between complimentary support and AppleCare besides the length of time they're good for? For various reasons, I can't make the 70-mile trip to the nearest authorized tech location, and I need to mail my computer in somehow.
