In addition to the big new Spring sale happening on Xbox Live, Microsoft is offering a pretty sweet deal on Xbox Live Gold. If you're a new subscriber, you can get 3 months of Gold for only $10.

That's a pretty nice deal, considering 3 months of Xbox Live Gold normally goes for $25. You need Xbox Live Gold to play Xbox One games online (for the most part) and to take advantage of other subscriber-only benefits such as deeper discounts on deals. You can sign up on Xbox.com right here (via Slickdeals). Again, this deal is only available for new subscribers to Xbox Live Gold.
