I think tank coins should be earn in game; not for money or survey (because only american have survey and im not american; i dont have so its not fair) so every body will have fun! Example: win 1 battle so i earn 1 tank-coin; win 3 battle continously earn 4 tank coin; 3x score earn 1 tank coins; win a deluxe-tank earn 1 tank coin;....This is not low price. You play much i know! Vote up so kChamp can see this( if you want or if you dont mind) kChamp please do this : }):*
