Hello, this is a great table. 
Hi, I'm interested in your coffee table.  I see you are asking $500 for it.  You mentioned that you topped off it's scandinavian-inspired silhouette with a sleek marble surface.  Did it come this way or did you do the marble surfacing yourself?
That's how it was when I got it. 
Oh ok, great.  Are you willing to accept $300 for it?
This table is worth at least $600. It's very sturdy. My 200 pound wife sat her fat butt down on it, and it didn't even creak. 
So you are giving a $100 discount from what the store sells it for?
Yes, although I bought it on sale the day I got it. 
I am willing to give you $400 and that's only if you deliver.
I can only stretch shipping at at least $475
Then $350 and I'll pick it up.
$425 with shipping, take it or leave it. 
Sorry, but knowing now that your 200 lbs wife sat on it.  The most i'm willing to pay is $400.
