I am wondering if there is a report that would let me see how much I, the owner of the store, actually paid for postage when shipping out an order. I can see a CSV report that shows what the customer paid, but I don't see a column for what I actually paid. For example, a customer may pay $4 for shipping and handling, but it may only cost me $3.25, or it may cost me more than $4. I'd like to be able to see a report that gives me both of these numbers. Thanks in advance.
