Input (English): Seller: hi, are you interested in buying the chairs?
Buyer: Yes. How long have you had the chairs?
Seller: A little over 6 months.  After bringing them home we decided we no longer wanted them.  They are in a smoke free environment and are excellent chairs.
Buyer: Can they be delivered?
Seller: If you agree to my asking price I'll deliver them and throw in a slightly used 8 x 10 contemporary area rug.  Agreed?
Buyer: How about $75 for both chairs and the rug if I pick them up
Seller: $100 is the least I'll take for both chairs
Buyer: can we do $80. I would have to rent a truck 
Seller: 100 plus the rug and I'll deliver
Seller: 

Output (English): rejected
