I purchased a second Arena REQ Bundle through Amazon and was able to redeem the code via xbox.com. When I investigated why I wasn’t getting my Arena REQs I found the threads on this site about the Warzone REQ Bundle and how only one purchase is allowed. Does the Arena REQ Bundle behave in the same way? If so, what recourse do I have? Did I just waste my money?
It does indeed work the same way OP. You can only redeem one bundle per Xbox Live account, it should tell your that on your bundle card
