Hello
Hi, I'm interested in the chair.  It's listed for $50.  Can you go any lower on that price?
Yes I can. How much are you willing to spend on it? I am sure we can make a deal. 
Oh that's good.  What color is the fabric?
It is blue. It is used as well.
I can give you $25 cash and I'll pick it up.  I was hoping on a brown color.
How about we do 35 dollars and I will deliver it to you? 
That sounds very fair.  $35 dollars it is.  Thanks
