Ok, I've half-heartedly tried to get myself some form of credit/debit card but the fact is the banks etc don't wanna know. I'm 17 years old and I want to play. So I ask this, and this only:

Would it be acceptable to send 20 english pounds through air mail for 3 months play? (I think thats about 30-35 bucks) I'm out of ideas, otherwise... =/

I don't use it myself, so I don't know any details on how it works, but there is a PayByCash option on the subscription screen, which says it "supports several other payment methods," which might work for you. But it does add a service fee.

That's partly what I'm worried about...

Money in the postal service is generally a bad idea.

Ahh...come on. The service fee couldn't be more than a few bucks, could it?
