Example Input: Seller: Hello
Buyer: Hello, what kind of phone does it come with?
Seller: It comes with a Samsung phone.
Buyer: yes, they make a few. What kind?
Seller: I am not sure. I only see what the ad has.
Buyer: Ok, we're supposed to be acting as if we're the buyer and seller so at this point you could look up or make up a phone
Seller: Galaxy S 3
Buyer: okay, your price is a bit high for an older model phone. Would you be willing to take 200?
Seller: 200 is a bit too low. Would you be able to go up to 225 at least?
Buyer: Does the phone come with any accessories (charger, case, etc.)?
Seller: Yes it does. It comes with a SIM card and I will throw in the case and the charger at no additional cost.
Buyer: okay then, 225 sounds good

Example Input: Buyer: Hi I'm interested in your bike.
Seller: Hello. It's a great bike. It's a collectible. I'm wanting $180 for it.
Buyer: Ok, but I'm worried about the rust, do you know if it's gone through the frame?
Seller: No, it's purely cosmetic. A fresh coat of paint will fix that right up for you.
Buyer: Well it's a little more work than I care to take on. I'd like to get it for $90. I'm probably going to have to take it to a restorer.
Seller: It really won't need much work at all but I do have some wiggle room. $90 is just too low for the collector's item. I could take $160 for it.
Buyer: I'll bring my offer up to $110 but do you have a helmet I could have. Safety first and all that.
Seller: Ok. I'll take $110 for and throw in the helmet.

Seller: Great quality, I just have the one fitbit because I bought one for my son and wife but my son didn't want it
Buyer: Nice! So they work very well? Do you like them, do you find they help monitoring your workouts better?
Seller: Yeah, I personally have this generation one too, it's so nice to use with RunKeeper or the FitBit app it comes with. Do you work out a lot?
Buyer: Yes that's why I want to get one. I hear it makes working out a lot more efficient. I'm looking to spend around $30, whats the lowest you can sell me one for today?
Seller: Oh I only have this one and it's literally in the box. Can you give me 50 for it? If you went to the store it'd be like 80
Buyer: Okay, since its fresh and still in the box Ill do $50. Thanks a lot for your help with this sale.
