Task: Dialogue State Tracking
Input (English): Seller: Hi, you want to get the storage unit?
Buyer: I do! No pics though. Could you do $15? I'm broke and trying to pay off my student loans. #thestruggleisreal
Seller: I took pics but I couldn't figure out how to upload them. I'm technologically challenged. they are new and still in the box, I got the wrong color and the store won't take it back so I'm selling it for $26.
Buyer: Yeah, well I'm financially challenged. $18 is all I've got. Cash today, I can come pick it up! And bake you some cookies.
Seller: Lol. Sure. You've got yourself a deal
Buyer: ;) Thanks!
