Ebay can go very, very wrong sometimes.
I had one guy who refused to post an item because I lived a £7 train journey away from his brother, who he said could just hand the item over (the postage costs were about £1).
Another guy claimed the item was posted and then that it was lost in the post and then that he was his sister and he had died suddenly and when he sold the item on again, left sarcastic comments (back from the dead) about me when I gave him negative feedback.
