I had an international purchaser who needed a change in their shipping (they requested delivery confirmation & insurance) after the transaction was already completed. I don't know how to adjust the shipping charges once the item has been purchased, so I created a custom listing just for the shipping price.
I'm sure there's a better way to do this, but I don't know it yet. What is the best way to do this for future reference?
Many thanks for the help!
