[Coupon Giveaway] 75% for Portal 2 valid until 14th of September 2012

Hello there SG.
I have a "Portal 2 75% off" coupon in my inventory which I don't need.
It will expire on the 14th of September, so you have today to get it.
I do it via forum and you will get it instantly, as I am all day online now.
I hope it's not against the rules, but I figured that before it goes to waste I can make someone happy in here.

So uh depending on how many people will actually be interested we can have a guessing game.
Guess my favorite number in the reach of 1-100.
Closest person to that number gets the coupon.
Only if 3 or more people apply for that coupon though.
If this is against the rules, please feel free to notify me and delete this little thread.
Thank you in advance.
