Task: Dialogue State Tracking
Input (English): Seller: Hi are you interested in this bike?
Buyer: Hello, I am very interested, but I can't pay your full asking price.  If you are needing it gone ASAP and are willing to negotiate on the price please let me know.
Seller: yes definitely. we can work on the price, but I can't go too low. I am already giving it at a discounted price
Buyer: Are there any additional perks or items that go with the bike you could include to make it worth my while?
Seller: I can give you the extra tires I had purchased them with the bike, and I never got to use them. They're brand new.l I can give that to you free :)
Buyer: Are they tires only or is it an extra set of wheels with tires?
Seller: Tires onl;y
Buyer: Hm.  Okay.  Well the bike is really nice and the tires will be helpful.  If I drive to you to pick it up with cash in hand would you do 650? 
Seller: that's too low. I can give it to you $900 nothing less than that
Buyer: If you can drive to me I can do 800 but unless you have anything else to offer with it I simply cannot afford to pay your asking price of 900.
Seller: Well I have already given you the tires. I can't do more than that. Take it or leave it then. I am sorry I can't go lower than that. 
Buyer: Then sorry I can't afford your bike.  Thank you though!
Buyer:
