Hi all. When selling a dvd I used Large Letter as the postage option (£1.55). However, when I went to the post office, they said it would be £3-odd! I couldn't understand a word he was saying, unfortunately, as to why it wasn't £1.55 - I think he said it was something to do with my hand-written label. But if I clicked on 'Buy Label' on ebay, that was £3-odd - what's going on(!) And what do I do now that the buyer has paid?
