Unable to Purchase Products in Marketplace

Hi
I’m trying to go the $120 route but the PC/Msoft is automatically logging me into my Game Pass a/c then only presenting the $95.99 discounted ‘With Game Pass’ option.
If I take that then presumably I have to keep paying the Monthly Game Pass fee?
How can I bypass the Game Pass option & just get Premium Deluxe , with out Game Pass?
Thanks
TG
(On reflection, I think the answer is to cancel the Game Pass 1st)
However, after cancelling Game Pass I find it is still ‘live’ in Microsoft’s ‘books’, until 2/10/21, as I had paid 1 month in advance.
So Microsoft still wants to give me the GPass discount for a Premium Deluxe purchase.
Presumably, if I accept that, on 2/11/21 the game will freeze as I no longer have Game Pass?
