Ah, so you got the 3-year AppleCare Protection Plan, eh?
I did actually, but only because the guy threw it in at the last minute for a quite amazing 80% off, this made it cheaper than buying from eBay as Tom suggested. It also covers the 24" LED screen I may, or may not, have bought at the same time
My advice, if you are buying a new Mac ring up and haggle over the phone. I was already going to buy it really, but decided to be cheeky and I got an even better deal and ended up with an overall 20% off.
I'm now skint, but I do have a big smile on my face!
Cheers
Cris.
