How do I send many forms?

[swanie]

I need many ASIN numbers from Amazon.com and
for this they have made a form. The problem
is that I need many ASIN numbers which is
the respons you receive from your sent form.
How do I go about making a script that sends
many forms, including film titles, and handle
the results. You can imagine the work it will
take to find ASIN numbers to more than 500
film titles.

Thanks for the help,
Henrik,
