Input: Seller: Hey would you like to purchase my bike
Buyer: Hi there. Yes, I am very much interested in it. Is it very old?
Seller: No only 3 years
Buyer: Wow that's a long time. May I ask why didn't you use it? Does it work well or are there any malfunctions associated?
Seller: Well I love the bike but I had been riding cross country on an endurance bike. So this has been fairly unused. No malfunctions I had made sure to periodically spray it with anti rust and anti seeze. Also it was left in a dry and secure environment.
Buyer: Okay that's good ti know. However, the price is very high for me. Is there anyway that we can work on that?
Seller: Yes but Id prefer to not go too low as I said before I love the bike and I am reluctuant to sell. Mainly selling due to me down sizing and lack of use.
Buyer: I can offer $390 as its old and has been sitting. Would appreciate it if you consider it
Seller: 390 is a bit harsh on me. Tell you what I can add a free delivery and a standard set of maintenace equipment specific to this type of bike
Buyer: What's the last price you can give me?
Seller: lets start at 550 and negotiate in increments of 10 from there?
Buyer: I can give you $500 honestly, I can't go beyond that because It doesn't fit my budget after that. ]
Seller: Ok 500 I can do and Ill also add a 1 year waranty on the chain to prove how sure I am of this bike.
Buyer: That's absolutely great! Thanks then we got a deal!
Buyer:
Seller:

Output:
bike
