How do i ammend an invoice for combined postage?
In the sold list, to the right of the item is a drop down menu.
Select send invoice, add the postage and DO NOT click re-calculate as that reverts it back.
Then you can preview to make sure it's correct and send.
Integrity is priceless. “I would prefer even to fail with honor than to win by cheating”. Sophocles
Add the postage you want to the postage area and then send.
DO NOT click on recalculate.
You can preview if you want before you send.
