Legit sites with non-steam giveaways (f.ex. Minecraft)

Is there any site where we can win games on other platform?
I know Indie Gala and some little desura sites, but I'm mostly interested in:

MINECRAFT :)

The price would never go down because of so good selling rate.
Still....

And I'm a poor , really poor student.
My work (little) don't give me to much money either... :(
