My mother ordered the set of Ray Prouty books for my Christmas prezzie last year. She placed the order around about AUgust/September and later gave up a full-time job in order to chase it.
I have just asked her if she had the contact name and number of the chap she spoke to at Mojave Books but sadly she lost it in a computer crash.
I did get the book in time for Christmas (2005 that is!).
Try to find a phone number - it might help!
Cheers
