Example Input: Seller: Hey so I have a great phone for sale, it's in excellent condition.
Buyer: Hi, I am interested in a phone, are they brand new or used?
Seller: It's brand new, I didn't need them. They're $650 each, this is a steal especially since it's $150 off.
Buyer: I am a student and would want to work on the price.. is that an option?
Seller: I don't know about that. Do you have a family member or friend who might want one, the price goes down in multiples.
Buyer: I could maybe get my sister in on a deal but it would have to be a great deal.
Seller: They would get knocked down to $600 each. I could also include two cases and glass screen protectors.
Buyer: Wow, still too high, i was thinking, 380 each.
Seller: I can't go that low, the lowest I could go is $575. That's only if you buy 2.
Buyer: I just think this is out of my reach, price wise. I could do 415 tops each.
Seller: No, you're going to have to come up to $525 flat and buy 4.
Buyer: ha, we are so far from each other. looks like a stalemate. good luck!
Buyer: 

Example Output: phone

Example Input: Buyer: Hi, I see you are selling a table made from scraps from your shop.
Seller: Yes it is a great table. While it is made of scraps, many hours were put into it to make it a very stylish and valuable table. 
Buyer: I'm a little concerned that you can see light that would shine through the table.   Would you be will to sell me the table for $350?
Seller: $350 is a little low for me. I understand your concern about the light, but rest assured it is a great table. How about $420?
Buyer: I will accept $420 if you agree to deliver to my house at no additional cost.
Seller: I think I can do that!

Example Input: Buyer: Hey there, nice bike you have here. How long have you had it?
Seller: A few weeks.  Rode it for 40miles only.  I'm just too big for it :/
Buyer: Ahhh, thank goodness I'm tall and lanky then. My budget is limited but I promise I'll take good care of the bike.
Seller: I put a lot of work into it. So I'm glad to hear. What amount you have in mind?
Buyer: Closer to 1000. My budget is 750 so I'm trying to make you a reasonable offer.
Seller: Oh no way man.  Only 40miles.  If I don't get 1500 I lose on this deal. 
Buyer: Well that's fine, that's just unreasonable; I can't offer list price, sorry.
Seller: 1500 is below list. Just saying. 
Buyer:
