I'm trying to add an additional link to each product listing. So that at the end of the summary text, there is a [more info] link there as well.

For example, on this page:

http://www.turtlecontacts.com/au/vio...ct-lenses-c-71

so, after:

new look you've...
These are a great...

they look like:

new look you've...[more info]
These are a great...[more info]

Where can I make this addition?

I've looked in
templates/<mytheme>/templates/tpl_modules_product_listing.php
templates/<mytheme>common/tpl_tabular_display.php

But neither of these files seem to contain what im after. Help! :)
