Hey. Can i interest you in some lamps? 
Yeah i'm interested....would you be willing to go to a lower price?
As long as it's reasonable. :)
Would you be willing to accept $75?
I'd probably be persuaded to go with 100.
That's a bit out of my price range...how about $85?
At the 120 range, I was losing money. How close to 100 are you willing to go?
Alright...I can go to $90, would that work?
Split the difference,  you got a deal at 95. That's 25 off. . .
Would you be willing to deliver the item to me?
If you're local. I have a truck, could swing them by. 
Yeah i'm local.  It's a deal, $95 and you deliver.  Thanks
