Welcome to the Club,
Search google for the best price on the PCGEVPW2 VAIO Plus 2: +2 year warranty from Sony. I purchased mine from Sony Style £169. Be careful as they need to deliver the pack tor you to obtain a nine digit number inside the pack. If it is lost by UPS or more likely by DHL you will need to prove you purchased it and it was lost by the courier. (This happen to me but it was kindly honoured) Give the number to Vaio Link and voila 2 year extension. The other thing is you can only purchase it within your first year warranty period or you will need the more expensive 3 year pack.
