Wow, this looks great!
It is in excellent condition.
Great! New?
I apologize, this piece of furniture has had nail polish remover spilled on the top of it. So it actually needs refinished. 
Not a problem. It will just effect how much I pay a little. How much are you asking?
I'm asking $650 for it as it is an antique.
How about 575? I'll pick it up and pay it in fill.
That's fine! I will accept your offer. I only take cash.
