Oh, I didn't know about this thread. I've got a bunch of unused humble bundle keys (including some recent ones like Owlboy and DoW3). Can someone explain to me how it works please, is it they send me their email via dm on the forum, and then I gift it to that email address via the humble store? I'll see about getting a list together.
Edit, they don't let you gift old stuff so my list isn't as long as I thought. Anyways, I've got up for grabs
Warhammer 40k Dawn of War 3 Undertale [gone]
Sonic Generations [gone] Black Mesa [gone]
A lot of games get repeated over bundles, but then I'm like, I want one or two games in that bundle, so for $5 I get the whole thing.
And then sometimes a game'll be on a daily deal site for, like, $1 and I forget that I already owned it.
