Can't buy opt cause they "don't sent in italy"

Hi all! Yesterday night i claimed my invite for the opt, but when i try to pay it and confirm my order, the site say that they don't send the opt in my country (italy). I tried to change the flag at the bottom of the page, selecting italy, but it don't work everyway! I have just a few hours, then my invite will be lost, so someone can help me, please?
