I got 2 unique codes each for 1 month of Game Pass Ultimate. I redeemed one and got another month free by turning on recurring billing. I turned off recurring billing just now.
I want to hold on to the second code in case the extra free month offer shows up again. Does anyone know how often Microsoft doles out those offers? Obviously, they won't offer it every time you redeem a code 'cause that would incentivize people to buy fewer codes and they're not stupid. Is there a way to somehow trigger the offer to come back again?
