I have had the same person buy 2 items, they have the same name, address, etc but have used 2 different buyer ids. I would like to combine the postage to save them some money but if I do that when I go to enter the tracking I can only do so for 1 item because of their 2 accounts, how can I get around this & prevent getting defects for not providing tracking on one item?

Have they asked for combine postage?
