I'm sorry for asking to make many people happy. But seems like many people here are only caring about the value of things and not making people happy. Topic closed since noone here wants to make more than one person happy.

Users who own “Half-Life 2: Episode One” and then go on to purchase the "Half-Life 2: Episode Pack”, “Valve Complete Pack” or
“The Orange Box” will receive an extra copy of “Half-Life 2: Episode One”.

I already own Episode One, and I want a copy of Orange Box badly. I offer anyone who wants to make THREE people happy.
How to:
Gift me Orange Box (this makes me happy).
I give you the extra copy of Episode One (which makes the winner of the said giveaway happy).
And you'll be happy too because you just gave away a copy of Episode One to a lucky winner!
That makes 3 in total! What a deal!

On a side note: If you don't have anything good to say or try to remind me rules, spare me the lecture and save your fingers a trouble.
If you've got a question, I'll be happy to answer.
