Right now Xbox One and Xbox 360 owners can grab a great deal on an Xbox Live Gold membership. Instead of the usual annual price of $60, you can get a 12-month Xbox Live Gold subscription for $40 from the Microsoft Store. That's a 33% savings on what's already a pretty great deal for Xbox owners. The offer ends August 1.

The deal is good for new members and current members alike. If you're already in the middle of an Xbox Live Gold subscription, buying this will add 12 months to it.
