I regret the delay and also the lack of communication. Our customer support person suffered a death in the family and has been offline for the past two weeks. Chris and I have been carrying the load in his absence, but some communications have regretably slipped through the cracks.
Though books to Europe were shipped by First Class mail, because most orders were in late November and early December, they got caught up in the Christmas mail / package rush. Some have arrived, and some regretably haven't.
There's no way to trace mail, so I'm afraid that all we can suggest is a wait of another couple of weeks. If it doesn't show up then we'll send another.
Sorry for the inconvenience.
