Just looked at John's website Carney Magic
and the second printing is due to be shipped on September 20. The price tag is still the same...$ 58.00 postpaid, and I recommend the book highly.
Also of note is the release of a brand new DVD called On Palming
that looks quite good. He's also got a nice special deal if you want to pick up his four recent DVDs at one time.
Hope this helps!
