how can I use imacros to extract product links from amazon?

I am trying to extract product links from amazon because
the products I am looking for are in all different categories
so there is no simple way to find them.

I made a simple imacro script to grab the links and
I added a loop, but I tried running it as play loop
but it does consistently get all the links.

Is there a free imacro out there that can extract
product urls from current page and also click
on the next pages and extract those urls?

Webharvy is easier to use. Go check that out.

What operating systems does it run on?

I like the portability aspect of iMacros

iMacros sounds a bit bloated for what you're trying to do. You can probably just use cURL and regex to grab all the links quickly.

Loop through the pages by changing "page=" in the URL, and then grab the links from the DIV with the ID "resultsCol".
