Extension for Magento shops to show expected discounts on product page.
This extension was developed for Magento 1.7, but it could also work for older versions.
Make sure to have disabled Magento compiler before installation.
Install via modman:
modman clone <this repository url>
Clear your cache.
Actually, there is nothing to configure for this extension.
Set up some cart price rule. If you watch a product, you'll now see the expected discount.
Just use Github issue tracker. Of course, you could fork this repository and make a pull request.
