Example Input: Seller: Hello
Buyer: Hello, what can you tell me about this item?
Seller: I'm selling a GoPro Hero 3 black edition with a waterproof case. It has an 8g memory stick and the charging cable. It is in excellent condition and works perfectly!
Buyer: Does it come with the original box?
Seller: Sure does! I didn't really use it much. I've only had it for a few months.
Buyer: What are you asking for it?
Seller: Well, they retail for around $379. It is slightly used so I'm asking for $130
Buyer: Will you deliver it?
Seller: Yes. The $130 includes shipping!
Buyer: I will pay you 98 for it and I will come pick it up.  Since it doesn't come with a warranty I dont want to risk paying to much.
Seller: Hmm, 98 is a bit too low for me. I'm looking to get back some of my money here. The item is basically brand new. How about $120?
Buyer: will you throw in a warranty with it?
Seller: It's still under warranty. I've only had it for 3 months and I believe the warranty is good for 2 years.
Buyer: Ok deal
Buyer:

Example Input: Buyer: Hello! Why are you getting rid of this router?
Seller: I got a new router as a gift so I don't need it anymore. 
Buyer: Cool. Benefit to me! But your price is quite high. You can guy used for $8 easy. Do you have some wiggle room
Seller: Actually this is the one that gives you extra speed, the regular one used is around 8 but this one used is about $15. I can go down to 12 though. 
Buyer: Yeah, def can't do $12. Budget won't allow it. Could probably swing $10 if you could throw in all the needed cables.
Seller: Okay I can work with that. It comes with all the cables too so that works.

Example Input: Buyer: Hi, I'm interestsed in this typewriter. Can you tell me whether it has ink and works effectively beyond just powering up?
Seller: Yes it has ink, powers up, and does what it should as it is in excellent condition. 
Buyer: That's great. Would you be willing to sell it for $25 if I come pick it up?
Seller: No I'm sorry I can't go that low because it is in such great condition and comes with everything needed.
Buyer: What about $30 if I make a deposit in advance?
Seller: Again I am sorry. I got an offer already for $75, but because I like you I could take $55. But that is as low as I can go. 
Buyer: If that is the lowest you can go then okay.
