How much does dc universe online cost per a month

it cost 15 bucks a month and the disc is 50, so don't waste your money thinking it's free forever. I just wasted 50 bucks

the above is NOT true.
its free, you get the full game with very little restrictions and all levels and quests for free. ONLY if you wanna be a legendary member you pay monthly. thats a free choice, i play for free and i have 2 max level characters and im experiencing the game to its fullest.
