I've got a question and i think it's really stupid, but how can i put money into my psn account to buy demos and things? are the stores selling the so called playstation cards for $50 or $100 bucks? 'cause i've checked in the online sites of the stores and there's no sign of them or does it has to be via credit card?

It depends where you are in the world, if you are in Mexico then I think the only payment method available to you is by credit card.
