Humble Bundle

A collection of games to buy?

Extremely cheap games, bonuses added in seven days time.

There is also a weekly sale every week which lasts for seven days.

You can pay $1 for most of the games or beat the average for some others.

here you go , got this explanation from wikipedia:

The Humble Bundles (previously known as Humble Indie Bundles) are a series of collections ("bundles") of video games, music albums or eBooks that are sold and distributed online at a price determined by the purchaser. The bundles are typically offered on a semi-regular basis during a two-week period; sales often include bonus games or media offered mid-week through the sale for those that have already purchased the bundle or otherwise pay more than the average.
Early bundles featured independently developed, multi-platform games (including Microsoft Windows, Mac OS X, and Linux platforms) provided without digital rights management (DRM). Later bundles have included those geared towards games from established developers, games for Android-based devices, bundles promoting game jams, and in two cases, a bundle consisting of mainstream titles from a major publisher. Sales of bundles are split between the developers/creators, the Humble Bundle operators, and one or more charities including Child's Play, the Electronic Frontier Foundation, charity: water, and the American Red Cross, with the buyer able to set the revenue split between these groups.
The first bundle was organized and managed by Wolfire Games. Beginning with the second bundle a separate company spin-off, Humble Bundle, Inc., was founded with financial investment with the sole purpose of organizing and managing the sale of these bundles. Several of the bundles have brought in over $1 million; the twenty-one completed bundles as of February 2013 have raised more than $33.2 million.[1] The Humble Bundle approach has created a number of similar efforts to offer "pay what you want" bundles for smaller titles, including Indie Gala and Indie Royale.

you can buy bundle of games and such on that site, for a minimum of 1$ in order to get steam games

The power of 1 dollar is greatly enhanced sice these bundles exist :D

You've been answered I think.

I can't wait to get the Dead Space 2 and Bulletstorm keys once they become available in humble origin bundle :D , anyone thinks there is a chance they add Mass Effect too?

It's a bundle website for (Hopefully) Steam games. But it can include other software games, most the money is designed to go to charity and you can get 3-15 games for a great deal!

basically its exactly what you see. I don't understand the question?

but as an alternate answer: well it used to be a bundle site with very cheap games(pay what you want) for charity, and supporting drm free crossplatform indie games. basically something to encourage ports to Linux and help indie devs get their names out there and send some $ to charities.

...but then for some reason it morphed into what it is today which is fairly self explanatory.
they dropped some requirements and stopped supporting some causes, but its still pwyw and charity and cheap

I believe the answer you are looking for is, "the shit."

It's literally on their site -_-
