[Q]: Seller: Hi are you interested in my zip bike?
Buyer: Hi. Yes, it's a nice bike but it's kind of old.
Seller: True but I just had it tuned up. My asking price is $400 but it's negotiable.
Buyer: Are there any defects I should know about? I was thinking $200 would be a good price for it.
Seller: No defects, I don't think I can take $200. What if I deliver it to you, can you come up to $300?
Buyer: If you throw in some knee pads and a helmet I could come up with $240.
Seller: Hmm, I do have those and won't have any use for them. $250 with drop off, safety gear and an extra chain I have laying around?
Buyer: Ok. That sounds perfect. $250 will work.

[Q]: Seller: hello there .. do you have questions?
Buyer: I saw your ad for the appartment, I also noticed it was in Elmwood, kind of a sketchy neighborhood. Would you take $2500?
Seller: Elmwood is actually very safe and very convienent for anyone going to the university or wanting to be close to shopping and transportation. i am afraid you offer is a little low.
Buyer: I just saw on the news last night that an elderly woman got mugged in Elmwood, so theres that. I can offer you $2550
Seller: I am wanting much closer $3600. I could do it for 3200 only because I would like to take care of it quickly.
Buyer: CAn we meet closer to the middel, how is $2700?
Seller: I would be willing to come down to 3000.
Buyer: With my salarym, I really can't go over $2736
Seller: Fine only because I want to do it quickly but not very fair to me.
