I'm working on a new website using osCommerce. It's for a specialty publisher, and when a new book is added, there are a group of customers (identified by a customer discount > 0) which automatically are shipped a copy of the book. I would like to know if there are any add-ons which would run a set of invoices for these customers when a new product is added (and hopefully create the appropriate shipping labels. They're all billed manually, so there would be no billing interface needed.
Is this an add-on (or similar to an add-on) that currently exists?
Thanks
Jeff
