So on their website it sais limited offer for the 6 months you pay $59.99
So if i wait till September 1st .. will i have to BUY the game for 59.99.. & THEN pay 60 more dollars for the 6 months?
Yes. Its a discount over the normal price of paying for 6 months of subscription.
So basically you get 1 free month from buying the game, then 6 months of play time at a discount. I believe you save around 20 dollars if you do it this way. Plus get some freebies, like Star Trek beta.
