I bought two gift copies of this bundle for $5 for the two. I thought I was being a little cheap at the time, but I recently learned that people are buying dozens of gift copies for one cent each. That really devalued gift copies for me, and I won't buy gift copies again unless I buy them for someone specific, because I don't think I'll be able to bring myself to pay less than $1.
(Edit: That was the shortest lived resolution ever. The new Humble Bundle is just out, and it not only has a $1 minimum for Steam keys but also has Android versions, and that really forced my hand to buy a spare copy.)
Anyway, I already gave one away, and here's the second one.
