Example Input: Seller: Hello!  Looks like you're in the market for an amplifier!
Buyer: Hi, can you tell me how long youu have had the amplifier?
Seller: I've had it a year or so.  We got another one and although we could still use this, we don't need two.
Buyer: That makes sense. What kind of accessories come with it?
Seller: You'll be set -- it comes with an analog to HDMI conversion.  You'll be able to connect to just about any network.
Buyer: Great. What brand is it?
Seller: It's a Marantz. Very reliable brand.  I'm asking $949 which is below market.
Buyer: Wow, ok. I have a budget of about 460 for a used amplifier.
Seller: Oh my.  That's lower than I anticipated.  How about $900?  Would that work?  I'll throw in our remaining Sirius XM membership.
Buyer: The XM offer is great, but that's still way out of my price range. Does it come with any kind of warranty?
Seller: There's about 8 months left on the warranty, which should help you.  How about if we meet in the middle somewhere about $725?
Buyer: I could probably pull a little extra money out of savings, although my partner may kill me. I could do 575
Seller: If you can do $650 while still on speaking terms with your partner, it's a deal.
Buyer: Well, you did say it comes with a warranty and the remaining XM membership. So, you've got a deal. 
Buyer: 
Seller: Sounds Great!

Example Input: Seller: Hello how are you today?
Buyer: I am doing well. I am interested in your bike you have for sale. I was wondering about the condition, is it road worthy? 
Seller: Hi yes absolutely its road worthy. Maybe the tires might need to be changed in the long run, but otherwise its as great as new
Buyer: In looking at comps, this bike i valued at far less. Because it needs new tires and there is no mention of upgrades, would you take 600? 
Seller: $600 is too too less for what you're getting. I can probably give it to you for $800
Buyer: Could we split difference and go $700? I can come pick up. 
Seller: This is a model of the year 1987 and we know old is always gold. I can sell it for $800 nothing less than that sorry. 
Buyer: I will $800, if you are willing to meet me in a central location that works for both of us. 
Seller: Absolutely we can work that out not a problem on my side!
Seller:
