hello I am selling my mosiac coffee table.
Oh wow that looks awesome!
My asking price is $450, its in great condition and can be used indoor only.
oh man I was sort of hoping to use this outdoors. Would you accept $400 for it?
I would accept $425 which I think is fair
I'll tell you what, I have 410 on me will that do?
yes sure $410 will work 
perfect, thank you.
