Well, I m glad this thread has been opened. I have had this question asked many times and in my humble opion, it is the worst way to begin a negotiated trade as it ends the negotiation immediately. Most of the times when asked this question, I have given them my bottom dollar which has always been a little lower than my advertised asking price and when they come back with an offer a little less, I just look at them and think to myself if they are trying to make a liar out of me or what, but I reply 'nope' and walk away. Now there are some people that will accept the fact that when you give them your bottom dollar that it is your bottom dollar and they will pay it or just say 'I can't do that'.
However, I agree that some of the above mentioned responses would be better as they would keep the negotiation alive.
