Very true Bloo. Even if you don't have your own card, I am sure that using your parents' card and simply paying them back each month wouldn't be that difficult.

Also, if you are over 11 or something, you are eligible for Visa Electron/Connect cards from banks like Barclays. It is very easy simply to say no to subscribing/donating, but please consider all the options since there is very little reason why most people can't help out.
