Good way of giving to charidee and getting a load of games for what ever you want to donate.

This time around all the keys are separate, so you can gift off the keys you already have.

Here's a good site to keep an eye on for this and other bundles.

And this one changes every few days for single games.

I follow them on google+. There are very few bundles that I don't pick up even if I have half the games. It's just such an easy way of getting those quirky steam games that'll probably never play but like the idea of playing, plus every now and again one turns out to be a real gem.

Awesomnauts is available. That was a game I've had my eye on for a while...plenty of others too.

The pay above average games are: hotline miami and proteus.
