Well, the cheapest way to go is get AppleCare off eBay, just prior to your 1 year warranty expiration if you can remember.this almost sounds like they are trying to get you to pay for being able to use the genius bar.. i know it doesn't exactly say that but it sounds fishy..
i guess me getting Applecare+ all depends on how much exactly my total will be on iDay
They are usually less expensive on eBay, and you don't have to get it on day 1 since there is a 1 year warranty.
They make it seem like it is a 2 year warranty, but it is obviously only a 1 year with some perks.
I guess there may be special circumstances, such as the free shipping as described, but if it is not too much of a hassle to get to the store, then the above procedure would be the way to go.
