Hello
Hi
Are you interested in buying the item I am selling?
Sure, but I can't pay the list price. Is $400 okay?
400 seems a bit too low for me. How about we settle at 500 dollars. That seems reasonable to me. How does that sound?
I really can't afford that.  What about $450?
475 and you got yourself a deal. How about that? I will deliver it myself.
Can you have it here by tomorrow?
Yes. I can deliver it then for you.
Okay, sounds good.
