Someone in Germany bought something. I didn't know they were in Germany. They then emailed asking for an invoice.
I said they could just pay. They then said as they were in Germany I needed to recalculate the postage and send the invoice.
I said my preferences were set to UK/domestic postage only (they are) and I apologised, said I wasn't posting internationally. And I relisted the item.
Why are they being allowed to bid/buy when my preferences are set correctly?
