I am about to get an iMac. I worry that it may break down once the 12 month warranty lapses. I have some question about this product that I hope you can answer. 1) Can I buy it anytime within the 12 month warranty of my iMac? 2) Does it matter that I buy the Protection Plan outside of the country? 3) How do I tie the Protection Plan to my iMac? Many thanks! I see on eBay a number of great deals on this product.
