even if the VAT would not appliable to users who can prove to be from another country .. then the site owner can always decide to raise the membership price because of his own VAT increases his costs to keep up the site .. so fencer could also say that he wont take any VAT into account for us users .. but that he has to increase the membership price because his own VAT is making it more costly for himself to maintain the site

(i know i could have worded that in better english ;))
