ok... I got a real head-scratcher I'm curious if anyone else has had this. We have a sales order from a customer that has a shipping method attached to it. Lets say, UPS. However, the order gets 2 fulfillments. 1st one is direct from us (via UPS) and the 2nd is sent "Best Way" as a drop-ship from a vendor. This "Best Way" function on the fulfillment has a zero shipping cost as they don't charge us to ship it. When we go to "bill" the Sales order though, the Cash Sale's billing amount is wrong. It shows zero cost to the customer for shipping because somehow the Cash Sale now shows the method from the last Item Fulfillment... What?!
