There is always a way to buy LFS licenses. The not-enough-money excuse has been covered many times, and can't really be helped with by anyone. But if someone has the money..
Paranoid parents? They don't like doing transactions over the internet? If you can't reason with them, then ask if it's possible to send the money to someone who isn't afraid of using their credit card online. As LFS has lots of users there are probably people in your country who could help you. Maybe ask around your native LFS community if they know of anyone who has helped people get their licenses before. If you then find a suitable and trusted person, just wire or mail (or whatever your parents will allow you to transfer the funds with) the money to him/her and get the license.
Maybe it's a big scam and we're all the same person? *insert relevant smiley here* (oh wait, found one ) :detective
Or else, more likely (hey, it isn't the flat earth forum ya know :razz, we've actually all managed to buy it. I was 14 when I bought S1, I got my own prepaid credit card. You could always find someone that you know who has a credit card, give them the cash and ask them to buy for you. Surely you have some relative or friend with a card?
What some people have done, is contacted another member near them, and actually got them to buy it, and gave them the cash. There's loads of ways. Plus there's paypal, you could link paypal to your bank account, and have it withdrawn from there. And no-one's the wiser Plus, if there's any trouble with payment, paypal will send you back the money.
