I recently saw a few Macbook Pros for sale and the guy selling it had provided serial numbers. When I put one in the Apple site to see the warranty, it said: "Our records indicate that your product is covered for service and telephone support under the AppleCare Protection Plan which is estimated to expire on June 04, 2012." I thought Applecare only covered up to 3 years. Even if they just bought it, shouldn't it expire in 2011? Any insight or explanation would be greatly appreciated; thanks in advance!
