Those are legal to give out, right?
They come free with games as a promotional code to demonstrate their brand, right. So understandably it would be no big deal as they are probably just lying around so there shouldn't be any legal liabilities involved.
It would be safe to assume that one would not be red flagged or TSA'd for sharing one online. These are in abundance afterall and if someone were to share a code online, o harm no foul, right
So, I guess the question is...I can has one?
