You could subscribe by Bank Transfer ... Dont know how it would work with currency conversion (Is that right?)
Have you anyone over here who could pay on your behalf?
Alternatively you could send a cheque ?
Sakar (Austria) doesnt do PP either and left me an amount of £££ when she was last over here, as a fund for English purchases and subscriptions.
Holiday to England coming up??? Or Anyone going over to the USA, willing to pick up payment on RS's behalf?
