You can buy PSN cards online (I'm from Brazil, so this is how I do).

I recommend eletronicfirst.com, cuz it's even cheaper than buying from PSN.

"PlayStation Network Card  £20

Our Price £17.99"

:]

I was hoping to avoid buying a PSN card but I guess I have no choice. 

To the Batmobile, Robin!!
