This discount is also stackable -- you can buy up to five codes to build a 15-month subscription at a discount. The deal is available for both new and current users, and works in any country that supports Ultimate Game Pass. 

The catch is that if you don't want to become a regular subscriber and pay$17 a month after the first three discounted months, you'll have to cancel your subscription within your Microsoft account before it auto-renews.
