Many people (14,712 downloads at last count) have benefited from my Zen Cart Quantity Discounts contribution. But sometimes you don’t want to discount all your products. That’s why I added the user exits exclude_category() and exclude_product() – to facilitate that kind of exclusion.
If you have used exclude_category() or exclude_product() to limit your Quantity Discounts, you should also limit the display of your Quantity Discounts Marketing text. Take a look at the notes on Zen Cart Quantity Discounts Marketing Text for instructions on how to do this.
