There is (or should be) a button that allows you to set up shipping charges based on the region you’re shipping to. It’s towards the bottom of the page that you are on, when you’re creating an auction or straight sale. Oops… having read your second post, I now see what you mean about changing the price for an extra purchase. I had this issue some months back; but I think Gary is right, you could just agree to refund the extra charges. It’s great that someone wants to buy a second pic!
