If you stumble across something called a “bonus code” for World of tanks, you should use it as fast as you can. These codes give you “goodies” inside the game, like Personal reserves, directives or consumables.
They are mostly (always?) limited in time or they can only be used a limited number of players. If you get one, log in to your World of tanks account via a browser, and in the upper right hand corner, select your profile. Then select “Activate Wargaming Code”:
Remember: Be quick!
