A friend of mine told me that these auctions that 
Celga is running are for someone else.  He even 
showed me his book that he received directly from 
the original seller (if you look at the Celga page 
you will see that the pages are scanned directly 
from the book).  Though he did pay something like 
$10 for it, if several people got together on one 
deal, then it would offset the cost.
