Hi there.
I am trying to achieve the same sort set up as Mary Kay Cosmetics has and I am wondering if Zen Cart is capable of doing this. Basically, a customer would go to the shopping cart system, view all of the products and add to cart any item. When checking out the customer has the choice of either checking out without a "consultant" id/referral number or inputting that "consultant" id/referral number. The system will also keep track of which "consultant" sold what.

Any suggestions?
