Quick reminder for new users and people who just want to learn more about Quantity Discounts: there is extensive documentation, examples, code fragments, frequently asked questions, etc. available on my home page. The link is in the readme file, or you can just go to my home page and click the Zen Cart link and search for Quantity Discounts.

I only update the readme file in the contribution when I update the software, but the documentation on my home page is updated constantly. Quantity Discounts is over three years old, so chances are, someone has had the same questions you're having and I've put answers on this page.
