A key supplyed from http://www.steamchampion.net/ which is a website that i have put together. It is still in its alpha stage!
Trusted Admins are the only users allowed to post giveaways on my site so all keys should be 100% working.
We try to post daily giveaways on steamchampion.net

If you want to see a video of the website in action watch this youtube video:
