Seller: Hey, I saw that you were interested in the bike!
Buyer: Yes I am interested what kind of condition is it in?
Seller: Its been used just a few times this summer, looks, and feels as if it was the day I bought it.
Buyer: So doesn't have any problems right?
Seller: None. You are welcome to come by, and give it a ride if you'd like.
Buyer: Are you willing to negotiate the price?
Seller: Ehh, not by much. What were you looking to spend?
Buyer: Can you do it for $600
Seller: 600 would be way too low for me. I suppose I could knock the price down just a hair if you can get here quick. How does $1100 sound?
Buyer: 800 and it would be going to a good home and I would really appreciate it.
Buyer:
Seller: I suppose you'd get more use out of it than I.. sounds good.
Seller:
