Example Input: Seller: Hi, I have this awesome car for sale. Are you interested/
Buyer: Hi, I'm interested in the CRV you have for sale.
Seller: Awesome. Do you have any questions about it?
Buyer: I am, but it's a little out of my price range, and I have my eye on a few other vehicles. I'm trying to spend closer to $15000. 
Seller: This is an almost new car in excellent condition. There is no way I can go that low. How does 21500 sound?
Buyer: I can't go that high. The highest I can spend is $18475
Seller: That won't work for me either. This car was barely used and I can get more for it elsewhere. My final offer would be 20000
Seller: 
Buyer: No, I'm sorry, you're being pretty unreasonable. That's only 10% off of what your original asking price is
Seller: Okay. I'll go elsewhere. You can reject the offer.
Buyer:
