Physical HW key for a steam key?

Not sure on the right way to do this, and a quick glance through the forum sticky didn't show me anything against it, so I thought i'd just throw this up in the general discussion.

I bought ARR in steam to try it out and had a great time. A friend of mine randomly bought me HW for me to pick up at a store, and at the time I didn't think the incompatibility through. So now i have a HW cd key i can't use, and i see a lot of other people have the same issue. If there's anyone who has a steam HW key that needs a physical key, i'd love to help each other out.

Might also post this on https://www.reddit.com/r/ffxiv/ just because there might be people there that don't frequent these forums.

I would love to, but the reddit specifically states no topics about key trading :(

i've posted on the steam trading discussions for ffxiv as well.

Thanks for the reply though!
