Steam is offering up a huge Indie Game deal right now until the launch of Portal 2 called the Potato Sack. It costs $38.65, and can be found here.
If someone is willing to gift it to me, I will offer all of the following:
My eternal love
All 5 episodes of Back to the Future (In the form of a code to do so)
Max and the Magic Marker (PC)
And just about any game OST you can think of.
If you're interested, PM me!
