Got a spare Arma 2 operation arrowhead?

I picked up arma 2 but realized you need OA to play dayz..... Shit haha. I dont have another 5 dollars to fork over right now, So if anyone picks up the Humble bundle and gets a spare ill happily take it off your hands. I dont have much time to paralyze the foursome these days so if your going to do a giveaway with said item please consider my plea haha have a good day guys.
