Example Input: Buyer: Hi, are you still selling the LG Stylo?
Seller: Yes I am.  It is a great phone.  I only used it as a back-up for about a month so it is in perfect shape with no signs of use at all.
Buyer: That sounds great. I am wary on the cost though. I'd like to get something for around 80
Seller: I really can't go quite that low as it does have an almost brand new otter box that comes with it.  That case cost me almost $60  I could go down to lets say 140
Buyer: With a brand new otter box?? Yeah I can do 140 if it comes with that.
Seller: Sounds good
Seller: 
Buyer: 

Example Output: phone

Example Input: Seller: Hello. How can I help yu?
Buyer: I see you have an iPhone6 available?
Seller: Yes, an iPhone 6 in Gold color available.
Buyer: I see it's in very good condition and unlocked. I am interested, however I dont have any of the carriers that this phone would require so I would incur an additional expense for that. Can you do $150?
Seller: I'm pretty firm on my asking price, actually. And that offer is extremely low for an unlocked iPhone 6. 
Buyer: I can find the exact same style online for less than $200. I'll even come pick it up from you, but $200 is pretty standard.
Seller: Well, I guess you should look elsewhere then, because I'm not budging from the 270 price point. Good day.
Seller: 

Example Output: phone

Example Input: Buyer: Hello! I'm interested in buying your car.
Seller: hi, do you have any questions?
Buyer: Yes, I do. Are there any problems with the car that maybe weren't listed that I should know about?
Seller: no, it is still quite new and in great condition
Buyer: And it gets good gas mileage, correct?
Seller: yes, it gets well above average gas mileage
Buyer: Sounds great. I can afford to buy it for around $10000. Is that reasonable for you?
Seller: that's a little too low for me.  I'll split the difference with you and accept 11,500
Buyer: That sounds reasonable enough for me. I'd say you've got a deal!
Buyer: 
Seller:
