I sold an item for £25 last night. I got a message later from the buyer saying that they would have to pay next week but the would mark the item as paid so that Ebay wouldn't "bug them". What should I do? I'm a bit cross that they have bid without the sufficient funds and that they could have been a bit more apologetic. How long is acceptable to wait and if they mark it as paid and don't would it be too late for me to dispute it?
