The people asking what's the lowest price and such and most likely to be time-wasters. This applies to all transactions, I find. Of course, there are cultures where haggling is the norm so, in these cases, it's best to start with an artificially high price which enables you to keep making concessions until you reach the price you wanted anyways.
