The $1 for 1 month Xbox Live Ultimate is back on (it was $2/2 months before). It does not stack with Ultimate Only with Xbox Live Gold offer.
This is a targeted offer, as with previous similar deals.
Note: this will convert any Xbox Live Gold you have left, to Xbox Live Ultimate, so you may want to top up your Xbox Live Gold first (if you can get a good deal).
I am already using the 2$ for 2 months thingo. Can we add this on to that? Or does it have to be a new account?
