Hello, I would like to ask if you trade humble bundle cd-keys, even if you do not trade them, I am looking for a few old bundled ones, so you might have a few and I'm ready to offer some games from your wishlist, in case you are interested - accept my friendship, I'm also ready to go first if we find decent trade for both of us, thanks
