I adore my new 17" MBP, which I bought from Best Buy but without their warranty plan, but I would like to wait a couple of months before getting AppleCare for it. I recall reading I have up to 1 year to decide, but that source may not be correct. Can I get AppleCare through amazon.com or can I get it directly from Apple? If the latter, can I get a discount by showing my student ID? Or do I need to get it now? Thx!
