Question about Microsoft Xbox Live Gold -12 Months

My recommendation would be to buy 2x 12Mt Gold, which will bring you to 100-120 CHF.
Once you have redeemed this, go to the Xbox website (you should be logged in).
And click on try Game Pass Ultimate... what happens is that the whole 24 months are converted to Game Pass Ultimate.
In other words you have Game Pass Ultimate for about 5-6 CHF/month :)

P.S.: If you already have Game Pass Ultimate running, just wait until it expires again (don't renew automatically).
And only then redeem Gold and then buy Game Pass Ultimate again.

I've been doing this since July 2017... works wonderfully every time.
Cheers!

This refers to the online service and is not linked to a console. However, I would recommend the GamePass Ultimate directly. This includes Live Gold, among other things.
