Pro-tip: You don’t need to own a XBOX to get these. Just claim them and ignore the “device not found” message. You’ll have them linked to your account anyway.
To get them stay on their respective pages and country locations and press the blue button below their prices.
Edit: I’ll be using this thread to post about all the XBOX freebies I can find.
