Task: Dialogue State Tracking
Input (English): Seller: Good morning.
Buyer: Good morning, so I'm interested in your sub and amplifier. 
Seller: It's a great set.  I am the original owner and am only getting rid of them because I bought a newer set of speakers.
Buyer: Is there anything wrong with them?
Seller: No.  Just had an opportunity to purchase a newer set and didn't need both.
Buyer: Ok, so I can do $60, unless you throw some extras in/
Seller: I have a set of connecting cables that will run between the amp and the speakers.  Those are new.  I'm willing to deliver them to you as well.  No less than $80.
Buyer: I still can't go that high, you need to come down in price. I'll pick them up, but we can say $65 and use the $15 for gas because I'm 30 miles away.
