Can I ask why you're getting rid of the chair?
I am moving to a smaller apartment and I won't have room for it. Are you interested?
Yeah, I think it would go well in a room in my apartment.
Great! When do you want to come pick it up?
I think we ought to agree on a price first. What were you thinking?
I was thinking around $35. How does that sound?
Honestly, I was thinking somewhere closer to 15-20. Its nice, but I don't *need* it.
Can you do $25? 
I think I can make that work.
Sounds good!
