With out getting too specific, there is a vulnerability the buyer can exploit. The sales man has spent ages with the buyer rolling out his well learned techniques. This is helped if the buyer uses up as much time as he can bare. Which means unless he makes a sale, he has totally wasted his time. Time is money.<p>So, just at the point where he has totalled up his oh so great deal for you, and just as you are about to pay for the items, stop. Turn to the sales man and offer a deal of your own.<p>Two things happen. You have just taken control back of the whole sales routine, which suddenly changes your position completely not least because it refreshes your own sense of control. And second, the sales man is totally set off balance and facing the loss of the sale and his time. You can give a whole load of his patter straight back. "Because you are such a great sales guy, I would hate for you to lose this sale", "This offer of mine is a one time offer, could go home and order this lot much cheaper on line", etc.<p>At that point I start by offering 25%, yes 25%, and seeing where he wants to go. My reasoning for the low percentage is that is sends out a message about how much I value the product, and that despite everything the sales man has said, it hasn't worked. But, I might buy at a value I feel is right for me.<p>Having done all that, the pressure is off you, and you are freed up to make a rational decision, and being back in control makes it much easier to say, "No, thanks, but I'll pass today."
