Office 365 is proving to be a rather popular Microsoft service, and the company plan on making it a much more worthy purchase as they are now throwing in a free 12 month Xbox LIVE Gold subscription with every Office 365 Home Premium or Office 365 University yearly subscription.
The offer is available until September 28, so you don't have that long to redeem the offer. The offer is available in 38 different countries including the United Kingdom and Australia. Those who do redeem the offer can do so by logging into your Office 365 email during initial setup.
Update: This offer is available in the United States as well as those in the UK, Australia, Canada, and Europe. We assume this offer is only available to new subscriptions, but if you already have an Office 365 subscription, it doesn't hurt to go and check does it?
