Hello! You were interested in the Blue roller chair?
I am, but I'd love to see a picture of the selection you have. Description isn't the best
I wasn't able to list any pictures but if you'd like to come by and see it I'll be more than happy to accommodate you. 
Okay, I can swing by. If I think the chair, would you accept $12 for it?
I was hoping for at least $20 for it, I'll even throw in a brass desk lamp.
I can't do $20. I'm even coming out of my way since their aren't any pictures 
$17 is the best I can do, I can meet you today if you'd like.
Okay, sounds good. Deal
