I just went and looked at Amazon US and it says they are temporarily out of stock...maybe that is what is going on with yours in the UK, Pickled Pixie? They have them on preorder at the book depository in the UK for 19.95, it says the release date is Nov 30.
I am in the US. I've never had Amazon cancel an order just because it was temporarily out of stock. How annoying. I hope you are able to get the deck from the Book Depository. It's a lovely piece of work.
