I can't buy a game pass offer

I would also try to make sure that you are only trying to get the one month worth, and not the other monthly packages they offer.

Since it starts a recurrent subscription, it requires that you either have enough funds in your account to cover the next payment or you have a credit card/Paypal on file as well. You will only be charged the $10 up front.

It is stated quite often that Game Pass games are not permanent on the Game Pass roster and can be taken off and re-added at any point. The app usually tells you what is coming and leaving Game Pass which can be helpful.

I dont generally buy DLC for game pass games unless I plan to finish the game and the DLC in the near future. They also usually offer the Game Pass games on offer to buy if you own game pass.

It is a shame to hear you cannot play your game without either purchasing it or waiting for it to be added back into the Game Pass library (if it ever does)

Wow some titles have included DLC with their game pass ultimate offerings, this is Noel means common or guaranteed. It does not include any deals see in its game pass offerings. They do however offer a ultimate package which lets you just buy the things in the ultimate should you have game pass

Offer is only valid for new and inactive subscriptions. If you currently are subscribed to Game Pass you can't get this offer.
