Example Input: Buyer: whoa glitchy system
Seller: Hi, are you interested in the bike?
Buyer: yes. but it's kinda pricey for a 27 yr old bike.
Seller: I know, but this is a collector's bike. So people generally fix them up and only ride the bike to show off. It's actually worth quite a bit because it is so old, yet in decent condition.
Buyer: needing a handbrake isn't in a decent condition. tell you what. i'll give you 100 for it.
Seller: How about if I throw in a hand brake and you can install it yourself for $150?
Buyer: yeah that's not gonna work for me. 110 is the max i'd pay for a bike in this condition
Seller: Is there something else I can throw in to sweeten the deal?
Buyer: nah. 110, bike and the handbrake. if that's ok we got a deal
Seller: Okay deal.

Example Input: Seller: Would you like to buy a Ballistic iPhone 5 Hard Case?
Buyer: Hi does this case come with a glass protection
Seller: Yes, it has a built in screen protector. Just $5
Buyer: Will my phone break at all with this? And can you do $3
Seller: No, your phone will be safe with this. I think $4.25 is more than fair.
Buyer: I mean they don't make iPhone 5 anymore and I really like this particular phone and don't want it to break
Seller: I can understand that. It's a very hard case, very durable. It's also shock-absorbent in case you drop it. This thing will definitely protect your phone, very little risk of breaking. $4.25
Buyer: Will it protect in water?
Seller: Yes, it has a water resistant mesh that will even protect the speakers. It also has button & port covers on the case. Want it?
Buyer: Yes I do want it but I honestly only have $3 and I think I'm doing you a favor by getting this off your hands
Seller: It is an older case, but there are still a lot of iPhone 5's out there. This case is in new condition as well. $3.00 is just too low. what about $4?
Buyer: Amazon actually has this same case for a $1 i was just instrested in your case because of the color
Seller: It is a lovely shade of blue. The lowest I can possibly go is $4. That's less than a sandwich around these parts.
Buyer: I'm asking you to kindly take $2 off...its just $2 i

Example Input: Seller: Hello. Are you interested in the bike?
Buyer: Hello, I see you are selling a bike?
Seller: Yes I am.
Buyer: How long have you had it?
Seller: I had it for about a year but hardly used it, because my daughter outgrew very quickly, and it was for her actually.
Buyer: Was it ever taken to the Mountains?
Seller: No only used it on the streets
Buyer: That's a plus. Did your daughter ever have an accident or fall off of the bike?
Seller: No thankfully she did not!
Buyer: Excellent! If you don't mind me asking, how much did you originally pay for it?
Seller: I had originally got it for $200 but I am now selling it for half the price
Buyer: I see. I like the bike. It seems like a good deal, but I am very hesitant to pay $100 for it when it is a year old. Is there any wiggle room on that price?
Seller: I could bring it down to $90 that's about it because its not very old.
Buyer: $90 pretty good, but I was thinking more along the lines of $80. Maybe we can meet in the middle at $85?
Seller: I can do $90 and that's about it
Buyer: You drive a hard bargain. Are you getting a lot of offers for it?
Seller: Yes I am. But I am willing to give it to you for $90. Are you interested?
Buyer: Since you did come down a bit, I guess I could tighten my belt at $90.
Seller: Thank you!
