I ended up buying it today. It won't work if you try to redeem it on Xbox.com. You have to redeem it on your Xbox one. I was able to get the dlc which was unlocked automatically too.
Any chance those Alan wake codes still work? I've wanted a digital copy and I've seen them on eBay but always hesitated to buy due to the chance of them being delisted. It would be great to get confirmation so I can pull the trigger next time. I've been dying to replay that game!
I use to not get these till about a month ago. Only thing I did different before that was I clicked on "Excellent" and filled out the survey near the bottom of an older email from them after it says "Please take a moment to rate this email:"
