Microsoft is currently doing a pretty good deal, where you can grab a month of Xbox Game Pass for literally a dollar. With Sea of Thieves hitting Game Pass last month and State of Decay 2 being available on release next week, you could literally pay both of these games for just a buck.
Obviously, you only get 30 days and then it rolls over to the usual $10.95 a month (still a great deal), so you’d need to ensure that you unsubscribed before the expiry date if you’re not willing to keep paying. You’d obviously lose access to these games too.
