Isn't that really this one?
http://shop.amcnano.com/Narduino-Arduino-clone-SKU2003.htm
(I believe run by the son of the Dr writing the book)
Typical E-bay, some yahoo will run the price up over the list price before the time runs out.
Price not much different now:
1 Narduino Arduino clone $11.00
Subtotal $11.00
Shipping (First-Class Mail®) & Handling $1.22
Tax $0.00
Order Total $12.22
and no savings on multiple qtys for shipping, $1.22 each one
3 Narduino Arduino clone $33.00
Subtotal $33.00
Shipping (First-Class Mail®) & Handling $3.66
Tax $0.00
Order Total $36.66
vs $9.50 + $2.28 for shipping = $11.78 on e-bay, if that price is still good tomorrow afternoon ...
