that may be so michael but jo-anne opened a thread saying she was looking for an item which frank has said he has for sale in a direct responce to jo-annes question, therefore in my eyes frank and jo-anne are discussing the potential sale and purchase of the item together.
it is not the done thing and is certainly not very nice to then come in and start trying to gazump the purchase, if jo-annes offer is not suitable then im sure frank knowing that theire are others interested will say so, up to that point the conversation should be left to the two original parties.
