Question: Seller: Hello, are you interested in the item for sale
Buyer: Yes I am interested but could you tell me what condition is it in?
Seller: Are you interested in purchasing this item
Buyer: Yes. What condition is it in though?
Seller: it is in great condition.
Buyer: Why are you selling it?
Seller: We've had some financial troubles this year. Just trying to make ends meet. 
Buyer: Okay would you take $2,000 for it? sounds like you really need the money
Seller: Unfortunately I can't go that low, I'm think more in the $3500 range. As you can see from the ad, this bike has a great deal of upgrades and customization. It's really a steal at this price
Buyer: Upgrades and customization don't really add value to something if you're selling it to someone else. I'll give you $2,100

Question: Seller: Hi
Buyer: Hi there. 
Seller: Are you looking to buy?
Buyer: I am interested in getting this pioneer stereo. It looks like old school. Does it work well?
Seller: It is in great condition, has a very high quality performance sound.
Buyer: Is the sound crisp? 
Seller: very and clear.
Buyer: How old have you had it for?
Seller: I have it two years. But still under warranty that would be transferred to you.
Buyer: Okay that would be great. Although the amount is too much for me. Can we do $120?
Seller: I am wanting to make a deal, but feel closer to $175 is fair.
Buyer: I could do $175 if you can deliver it to me please? 
Seller: yes I could deliver , no problem.

Question: Buyer: Good morning.  Can you tell me about the mountain bike you have listed?
Seller: Sure. Shame to let it go because of how much I love it, but it's great if you wanna go downhill. It has a raceface handlebars and stem evolve, WTB seat, moto and cranks and Maxxis high roller tires.
Buyer: How long have you owned it for?   Are you the original owner?
Seller: That's right. It's mine only, and I've owned for about a few months give or take, so it's not in the worst condition at all. How much are we willing to negotiate?
Buyer: Well, $800 is a bit higher than I'm willing to pay, but would you be willing to consider an offer of $650 if I were to come and pick it up?  Might save you a little bit of hassle....
Seller: That s a lot lower than I hoped it would be. I want to sell it for $775 because of how close it is to that of a brand new bike in terms of quality.
Buyer: Hmmm....How about $725?  
Seller: How about 750? $25 extra shouldn't be too far of a stretch from your current offer, no?
Buyer: Yeah.  OK.  I'll do $750 if you're willing to deliver it to me.  How about that?
Seller: I'm willing to deliver to you! Sounds good to me!
