I to have run into this and i am in Australia the vat surcharge that is ridiculously high.... thus if a mod is to be paid by SWREG i don,t buy it any more. i had things that where $5 US cost me $21 AUD and the exchange rate was very good plus the extended download service... what a load of make believe nonsense.
Should be illegal if you ask me in German would be called "Wucher" in English Legal robbery
Cheers
