Negitive rep because I prefer renegade option in mass effect games. Reason I have so many codes was because you could use 10 per day but it got fixed, although I was saving them for the 24hours of premium I could use over weeks ends.
Edit: the codes have probably been used by now, but you can get more from here:
Just click on the picture of tanks and put your email in. Don't check the box though or else you'll get spammed. When you get the code just go to the main WoT website, log in and then click on your name and you'll see a link called "Enter Promo Code".
