Arma2:OA Keys!
Reliable and cheap!
1 key = 7€
(I will re-offer the 2€/key deal soon, I don't have many keys left)
All these keys are "borrowed", but none should ever get an in-use error due to an update I did a few days ago.
PM me if interested with your Paypal email address and how many keys you want. Feel free to bump this thread / give vouch if you want to.
I'll help you change your key if you need help, but you shouldn't need it as it's pretty straightforward with my keychanger program.
Also yes, I am selling for omfghax0r now, because he's too busy with life to keep selling. These are all fresh working keys. Thanks!
