I had this on order for a couple of months at £375. Amazon's web site stated "Order now and we'll deliver when available..."
I knew it would be a long delivery period but no problem.
on 20/05 I received an email from Amazon stating "Our supplier has informed us that this item is no longer available. This item has now been cancelled from your order ...
I know this to be untrue since Nathan Myrvold replied to my posting on eGullet and we know from the MC blog that there are 25000 more copies coming soon.
The real give-away came when I looked up MC on the Amazon.UK page and was invited to register my interest in beeing informed when it was available... at a price of £465: an increase of 25% over the price I ordered it at and approx 55% more than it's currently being sold for in the USA
