Buy iTunes credit?

[Snubbs]

Is it possible to buy iTunes vouchers electronically? I.E. without having to go buy them physically/online and wait for delivery? Reason I ask is, I don't like the thought of my debit card being on their file (as say for instance my cousin gets hold of my iPhone and spends $$$$$ on crappy games, i'll have lost X funds...).

If I can't buy electronically, I guess I'll have to wait till I pop out tomorrow to morrisons.... :rasp:

When you use your card you have to enter a password when loggin into itunes, aslong he doesnt kno the password and you dont leave itunes on then your fine, itunes also logs out making you enter password again after a while
