Some ppl have suggested to do what you and I have done. Which is order more than one. But I wonder if having more than one order is actually having and adverse effect, like maybe slowing the process down. Just speculating.
Edit: In my case I used the same card to order a couple of watches. And a different card to order another etc. all tied to the same iTunes account.
My only fear is both ship at the same time, since i dnt have enough for both in my account.
