(EDIT: I edited this a little bit so it's a bit more informative, fun to read, and so it has more links and commentaries.)
The Humble Bundle Store is here! It's the first day it's opened, and because of this special occasion it's offering discounts between 50%, 66%, and 75% depending on the title!
Don't Starve - 7.49$ USD (50% off!) *DRM-free*, Steam key, works on Windows (duh), Linux and Mac.
Chivalry - 6.25$ USD (75% off!), Steam key, works on Windows (duh)
Natural Selection - 6.25$ USD (75% off!), Steam key, works on Windows (duh), Linux
Orcs Must Die - 6.25$ USD (75% off!), Steam key, works on Windows (duh)
Obviously, these are some pretty sweet deals, and 10% of the sale price goes to the follow charities: American Red Cross, Child's Play Charity, Electronic Frontier Foundation, World Land Trust, and charity:water. 75% of the money goes to the game's creator, and 15% go for "Humble Tip". You save money, you help your favorite charity. Everybody wins.

Please *NOTE* : here you're buying *individual* games, not a whole bundle. The bundle deals are temporary, the store however will offer discounts and will be available on a regular basis. So you can just hop on the Humble Store and help charities, while you also buy awesome games that work on many platforms. Think of this as a huge discount game store that sells online keys and that helps charities on the side, that's all.

So now, massive discounts AND giving money to useful charities (like EFF, to protect the very thing that allows the Tek to exist in the first place!) for the games we want. It's like a Steam Sale, except it's all year 'round.
I think I'm gonna open a bottle of Brazilian Cachaca to celebrate this one, and make myself some caipirinhas! I'll drink to that. A toast to cheaper games, and helping charities! Cheers!
