This has probably been asked before but I can't find any topics that answer my question..
I recently had a purchase from a US buyer (item was over 700 g) and unfortunately the $9 security charge was not added to the postage cost. The buyer paid immediately with Pay Pal and I am left with a payment which is $9 short. I called ebay to try and find out why their postage calculator is not adding the security charge and they were not helpful at all, could not give me an answer. I asked to raise a technical ticket but have no idea how long it will take them to get back to me. In the meantime I can't imagine what I should do to fix this. I have over 200 listings - do I start modifying all of them to remove US from the list? Contacting people after they purchased and asking for an additional payment is sure to tick them off - great way of getting a neg feedback.

Am I missing something? Has anyone else experienced this?
