Pricing Error on Amazon

Hi All,

For those who may be interested I stumbled onto a pricing error on Amazon
for the following book.

Learning Perl/Tk: Graphical User Interfaces with Perl (O'Reilly Nutshell)
by Nancy Walsh, Linda Mui
ISBN: 1565923146

The price is $3.49. Normally it's $34.99, it looks like someone transposed
a decimal point. I only have a mild interest in Tk programming, but for
3.50 I ordered it. The order did go thru and the book is on the way.
Thanks for the Christmas present Amazon!!
Peter
