DOC - Eccomerce Cart Bug Fix Plus Update

Hello, I have a cleint site and i just recently integrated a shopping cart. This shopping cart has a " Bulk Discount" ordering system. I believe i have programmed it properly, but it is not applying the discount to the order on check out. The other thing i need is when an order is placed I need the bulk discount to add FREE Shipping. In summary i need: - Bulk discount fixed (Example... Buy 3 products and receive 20% off plus Free Shipping) - Free shipping for bulk orders The ecommerce script is very simple to use and edit. I need this 2 things fixed TODAY if possible. This could take you 5 Mins or it could take you several hours - not sure. Thanks!
