Task: Dialogue State Tracking
Input (English): Buyer: Hi I am interested in your fitbit is it still available?
Seller: It sure is. It is in perfect condition and I am only asking $60 for it. Half of what I paid for it brand new. 
Buyer: Well I do understand that you did pay quite a bit more for it but the truth is, these are only 66 brand new from walmart now.  I would be willing to pick it up right away and pay you $30 for it
Seller: That is half my asking price. I'll take at least $50 for them and no less. 
Buyer: For $50 would you by any chance be willing to deliver?
Seller: Sure! I'll bring them to you. Just e-mail me your address or a meeting point and I'll head over. 
Buyer: 
Buyer: great thank you
Seller: 

Output (English): accepted
