Example Input: Buyer: Can you give me the measurements for the speaker?
Seller: I am sorry, but I am really bad at guessing dimensions. Perhaps you could look it up: JBL Portable Speaker On Stage Micro Audio Speaker System. I will say that it is quite small, but very powerful!
Buyer: And it puts out really good sound?
Seller: Yes! It's hard to believe such big sound comes out of this little bitty speaker, but the sound is loud and crystal clear. I paid $120 for it less than six months ago. My boyfriend just bought a new one and we have no need for this one anymore.
Buyer: It sounds great and I really do want it but, I'm not sure I can do 30. Could you go down 5 or 10 bucks?
Seller: Lowest I can go is $25 . . . and I'll give you four new batteries to put in it :)
Buyer: I think I can do 25. Thank you.

Example Input: Seller: Hello, how are you?
Buyer: Hello! I am good, thanks! I am interested in this furniture but $1150 is a pretty steep price with the missing fabric.
Seller: Well it is in excellent condition.  I have a friend that can make the covers for you.
Buyer: i can give you $650 with the covers thrown in. Not having the original fabric really takes the value down quite a bit 
Seller: You do have a point there.  $500 discount with me throwing the covers in is kinda steep also.  How about I let you have it for 750 with the covers thrown in.
Buyer: I can do $750 with the covers thrown in. You have a deal!
Buyer: 
Seller: great! glad we were able to agree.

Example Input: Buyer: Hi, I'm interested in your Motorola?
Seller: It's a great phone, very slightly used
Buyer: Any scratches, dents? Cracked screen?
Seller: No scratches at all anywhere. It's also compatible with all major carrier. It's a great deal I can assure you
Buyer: $120 is a little high. Does it come with any peripherals? A case?
Seller: I can give you my previous case that fits perfectly! And a pair of earbuds if you're really interested.
Buyer: A case would be great. I assume it comes with the charger as well?
Seller: Yes of course. I am telling you 120$ is not much for this phone!
Buyer: Can we do $100 for the phone w/charger and the case? Thanks but no thanks on the earbuds, I'm a bit of a germaphobe. 
Seller: Yes, but you have to pick it up if tht's ok with you.
Seller: 
Buyer: That would work great for me!
