Xbox Game Pass For PC Charged Me The Full Price Rather Than First Month Special Prize

The $1 charge is only for the first month. Once it's time for you to renew, you'll be charged the regular price. If you already have gold (and game pass) it will converted to the ultimate subscription. The Ultimate Game Pass includes gold, Xbox Game Pass,
and PC Game Pass. The upside is that you only have 1 subscription for all 3.

I use Game Pass on the console and sometimes on my pc. When I look at the pricing, in my area it would be 14.99 chf per month for game pass ultimate, 12.00 chf per month for standard game pass and 6.58 chf per month for gold (if billed annually).

Ultimate is cheaper for me even if I don't use game pass for pc, since purchasing game pass for console and gold seperatly is more expensive. Game Pass for PC is more like a nice have thing for me rather than I would really need it.

It should me free no price was indicated and its first time to subscribe. It just told me billing will be charged next month with full price

Usually you'll use the Xbox app. The games given there are for PC Game Pass. If a game is not included with Game Pass, it'll have a price listed rather than "included with Game Pass".

Much rather pay full price for a game that gives me hours/weeks/months worth of enjoyment than for a single player game I play through once.
