Own a 17" Macbook Pro from April 2010. I live in Canada. The Apple website calls the latest warranty for 15" and 17" models MD013LL/A. Most of the extended warranties on eBay are called MD012LL/A. This is the cheapest one I've found, and the one I want to buy: http://cgi.ebay.com/AppleCare-Prote...ting_Software_Software_SR&hash=item4cf84681ac What gives? Will they all work? Can I go for the cheapest one? Thanks, folks.
