Why would you buy that? That's ridiculously high, there's a lot of websites out there that sells Bitcoin at a normal price. It would even be better if you just buy from another user, meetup with him or simply contact him. That's not a huge opportunity at all because no one would buy at that price. You could even sell your coins for a higher price than that but you'll be just wasting your time and effort.
I asked how the coins were delivered and the seller said that a voucher for the coins on the exchange was sent. That way the buyer didn't get hung up on the fact that the coins could not be delivered to a BTC address. One million of these useless coins went off at $900.
I think no matter how your coins would be delivered, it should be not double the current price of it. Even if the coins are delivered with a box full of decorations, the amount of Bitcoin that you'll have would still be the same. I guess the seller is just sugar coating his deal by making use the guarantee part of using a voucher on their exchange site.
Nevertheless, I advise that you look for another seller of Bitcoin. I think you can buy Bitcoins at a fair price in almost every Bitcoin wallet out there except for crazy ones like the one you found.
