I'm only an ebay novice. I've sold a pair of trousers, well they went for 99p. My ad stated UK postage only with appropriate costs. I came to print a postage label and it turns out the buyer is in Oz. They haven't contacted me and have only paid for UK postage, if I dispatch I will be out of pocket. I have sent them 2 messages asking for the extra postage and heard nothing from them. This morning having tried to find an ebay answer I have sent another message asking if they want to cancel the sale. I have not yet left feedback. Sorry for the long post WWYD?
