I got an email telling me that the A cover was available for order today... although it's been available for preorder with the B cover for a good while now. I've already ordered it a couple of weeks back. (I'm just a bit puzzled that they're telling me that the cover I actually ordered is available for order, rather than both, making me wonder if this is a two part process.)
Nothing about dispatch,but as I ordered it after a lot of people I expect mine to be sent later. It's no problem.
I got the same. 2 emails telling me that cover a and cover b are available but no dispatch notice for the ones I bought.
Ah, so you ordered both James? I just ordered A and just got the notification for that one. So they're telling us the ones we preordered are available then. As I already sent my card details, I won't order it again. Could get a bit expensive.

Actually, I wonder if they're doing it this way to give us the opportunity to order the digital versions as well, if we want them, as I don't think they were available for pre-order.
I don't really double dip for format, and usually stick with digital, but as this is a bumper seminal issue, I decided to go the traditional paper route for this, but I know there are plenty who like both for convenience.
