I wanna know... there is a way to buy boosters by mobile? I don't even had a creditcard to buy in paypal, but i want to buy the boosters by using my cellphone credits. Have how to implement that?
(ps: i'm from brazil, and using my cellphone is the only way that i can do because i don't get a creditcard.)

um... thank you
how many time last the boosters?
did you know? forever?
