There are several examples here:

http://search.cpan.org/~jesse/WWW-Mechanize-1.70/lib/WWW/Mechanize/Examples.pod

I've written many scripts using WWW::Mechanize - I'll go through them and find a few examples that I can share and post them here.

I use the Mac Dashboard applet from Junecloud called 'Delivery Status' to track shipments, but I'm often not at a Mac when I get the e-mail, so I whipped up this script using WWW::Mechanize to add a package to my tracking list.

Usage:

  addpkg.pl --from DeliveryCompany --item "Cool New Thing" --no 123456789012345

The most important thing is usually to create the HTTP::Cookies object, as many websites use cookies for tracking.
addpkg.pl.txt

To use WWW::Mechanize there are 2 things you should know/do.  First, if you have Firefox with the Web Developer plugin, you can easily trace out FORM names and elements, which you'll need to submit specific forms.  The other thing is to just use trial and error.  I'll often call "print $m->content();" at various stages to make sure I'm getting the desired results.
