This is a great deal. I picked up both for the amount that one 12 month subscription card costs. I would however wait to use the card for existing accounts because it gave me 12 months from the day I used it instead of 12 months from the day my existing sub would run out. I called MS and got a refund on the difference but it's still a pain.
