Task: Dialogue State Tracking
Input (English): Seller: Hello! I have listed the price of the bike at $3450
Buyer: Hi. I'm wondering if you would be willing to accept a price of around $2000 instead. I'd be willing to pick it up from wherever you have it now.
Seller: I cannot go down that low. I'd be willing to knock it down to 3000, and throw in a bikelock with a custom helmet
Buyer: I'm not sure if I'd be interested in the lock and helmet. In what condition is the bike? I see you've written "brand new" in the description, and I'd be willing to go up to $2500 if the tires are new and the frame and chain are in good condition.
