Task: Dialogue State Tracking
Input (English): Seller: Hey so I have a great phone for sale, it's in excellent condition.
Buyer: Hi, I am interested in a phone, are they brand new or used?
Seller: It's brand new, I didn't need them. They're $650 each, this is a steal especially since it's $150 off.
Buyer: I am a student and would want to work on the price.. is that an option?
Seller: I don't know about that. Do you have a family member or friend who might want one, the price goes down in multiples.
Buyer: I could maybe get my sister in on a deal but it would have to be a great deal.
Seller: They would get knocked down to $600 each. I could also include two cases and glass screen protectors.
Buyer: Wow, still too high, i was thinking, 380 each.
Seller: I can't go that low, the lowest I could go is $575. That's only if you buy 2.
Buyer: I just think this is out of my reach, price wise. I could do 415 tops each.
Seller: No, you're going to have to come up to $525 flat and buy 4.
Buyer: ha, we are so far from each other. looks like a stalemate. good luck!
Buyer:
