Spare Half Life 2: Ep 1 & 2?

Hey guys,

Recently switched to Linux full time, was trying to flesh out my gaming library a little bit more. I was wondering if anyone has a spare key for either/or both? I have copies of Castle Crashers, Alan Wake Franchise and Deadlight if someone would like to trade.

I know the 'Orange Box' does go on sale periodically, I'm just impatient!
