This zen cart module will create a best-sellers page that can be accessed at ?main_page=best_sellers. Unlike the "best sellers reloaded" mod, this one does not have its own template, it uses the same template that is used for listing products.
The reason for that:

1. It keeps the mod extremely light weight.
2. Keep the listing consistent with the product_listing.

Includes installation and configuration of this module on your zen cart web site.
