Example Input: Buyer: Hello! I am interested in your oscilloscope.
Seller: Hello, you have great taste, mine is in excellent condition.
Buyer: I am interested, but $490 is a little too high for me. Considering there is a newer model out on the market, would you take $420 for it?
Seller: well, mine does include a 17" monitor, 2 probes and all of the power cords, I could do $475
Buyer: The highest I can go is $455. I think 100 Mega samples per second is a little low compared to the other models I have been looking at. Would you take $455? I will even come pick it up.
Seller: I would go to $460 and would be happy to deliver it to you if you're in the Bay Area
Buyer: Deal

Seller: No, none that I know of.  I just do not use them as much as I thought I would.
Buyer: Well, then I suppose I'd be willing to take them off your hands. I'd like to pay$216 for the binoculars.
Seller: My asking price $380.  I could go slightly lower but I can not sell them for $216, sorry.
Buyer: Well, what would your best price be?
Seller: $340 would be fine with me
Buyer: Well, I'd be willing to drive over and pick them up, if you can come down to $260.
