Easy peasy way to add 12 months to existing subscription, 1 Mar. 2014
My subscription was due to expire in a months time so I purchased this and clicked through after purchase, signed into my existing account and it added 12 months to my existing subscription. Saved money on the price I would have had to pay if I had renewed through Microsoft.
