I live in Europe, but mov ed here from the States. My Magix account is in the States along with my Stateside PayPal. So, since I am a "Stateside" user, I don't see the same upgrade offer as what you posted. I see a $100USD off upgrade price listing, nothing about Vitascene V5.
I would have seen it if it was for US users. And even if it was, a fake US address will not work. You have to have a US bank/PayPal account to pay for the product.
