Update: Amazon’s 6+3 month deal is still available, but if you just want to try out the service, Microsoft will sell you a single month for just $2, and toss in a second one for free.
With Xbox Game Pass, Microsoft basically created the Netflix of video games, and it’s a great deal at its usual $10 per month. But for a limited time, you can get a three bonus months when you buy a six month membership for $60. Xbox Game Pass grants you access to new releases like State of Decay 2 and Sea of Thieves, as well as classics like KOTOR and all of the Gear of War games. Even Fallout 4 is included now!
Just make sure you see the bonus months in the “special offers and product promotions” section of the product page.
