I have a client that I'm setting up a cart for. The cart's done but we have a bit of a tricky setup. He sells T-Shirts and they're location specific. So one shirt might be sold at one by one of his reps, another shirt sold at a second event by a second rep, and finally...online sales as well.
Online sales need to be including shipping. Event specific items need free shipping because the shirts are sold through an internet-enabled laptop, but immediately handing the shirt over to the customer on-site.
The separation of codes or something is useful so that he knows how to pay out commission for sold merchandise. Any help is appreciated. I'm under the gun to get this live ASAP so your advice is useful at this juncture.
