Task: Dialogue State Tracking
Input (English): Seller: Hi! Are you interested in the iPhone 7?
Buyer: Yes. I'm on a tight budget right now. Can you negotiate on the price?
Seller: I can negotiate a little, but I think $430 is fair. The phone is still under warranty until Christmas 2017, is in excellent condition, has always been in a case with a screen protector, and a new one costs a lot more.
Buyer: I understand. Unfortunately, I only have about $320 to spend right now.
Seller: Could you make it $375?
Buyer: If you are able to meet me tomorrow, I could probably get $370 in cash. Would that work?
Seller: Yes. See you tomorrow.
Seller: 
Buyer: 

Output (English): accepted
