Buy PC 1 Month and get 2 months free. You will be charged $1 for the first month, and got the next 2 months for free. So in total you get 3 months of subscription for $1.
Works for new members and inactive members. I cancelled my subscription 2 or 3 months ago, and was able to take this deal just now.
Great timing for the new Age of Empires IV, I was going to buy it from Steam.
Subscription continues automatically at $10.95/month unless cancelled through your Microsoft Account.
