No, thanks. Good luck trading these keys =)

No thanks, but I may accept that later. Stay in touch ;D
You can trade it with someone else if I didn't respond later.

Great offer, but I discussed the trade already with someone else (A friend actually), I'll contact you in case if he changed his mind.

Yes, its a URL. But the steam games there are used.

Edit: Forgot, I claimed the page. Sorry, they're separate keys.

All of Indie Gala Sigma keys (Except for Alien Hallway. Sorry, gave it away recently)
For origin Humble Bundle, most of the games (Maybe all?).

..Or you can mix both of them in your way and i'll see.

Note: Origin keys from HB. (Not steam)
