Task: Dialogue State Tracking
Input (English): Buyer: HI is this still available? Why are you selling it so soon?
Seller: Brand new, not even opened in the box, received as a present for christmas, this item retails at 2500.  I already have several TVs, but I don't even know where my friends bought this for me, and it's rude to ask them if they know I'm going to return it.
Buyer: Yes I can understand that. Does it need any additional equipment to connect the smart tv apps?
Seller: Everything is included.  It comes with one connect box, stand, smart touch remote, table top stand, user's manual and a power choard
Buyer: Geat, would you possibly take $1500 if Ic an come now to pickup? My tv just went out and I can't afford one from a store and I don't want to miss the next episode of Big brother when it airs
Seller: I'd really like to get 2100 at the lowest.
Buyer: How about middle road would you do? 1900
Seller: deal
Seller: 
Buyer: 

Output (English): accepted
