I've started selling a few bits and someone had asked for a buy it now price before any bids started. I suggested a price and then she wanted photos before she decided to go for it. In the meantime bids were placed so I couldn't add a buy it now price then. She said I can send her an invoice. What am I supposed to do? Can I end the item and disappoint all the other bidders? And how on earth do you send an invoice? Help! This is far too complicated!!
