The Visa Virtuon works like a regular Visa creditcard. I think you can order in the English shop too. Just enter the creditcard number, the expiration date and the security number, that should do. If you've got 199 Euro on your Visa Virtuon bankaccount it's more than enough to cover for your purchase in Dollars actually.

You live in Yugoslavia, oops, sorry I meant Serbia, right?

Cheers
