Hey so I'm interested in the bike you have for sale. Can you tell me about it? 
Sure thing. Frame is 17 Inches. Comes with a 3-speed Shimano nexus shifter. It works fine, but a tune-up and some new tires would help its performance greatly.
Woah, that sounds like it needs a lot of stuff. What kind of condition is it in?
Again, it's in great working condition. It doesn't need those things that I mentioned, but they would help.
So can you deliver it?
Sure. That won't be a problem. Will you be willing to pay the listed price for it?
Absolutely not, I'm thinking more $40. It needs another $100 in work.
That's a fair point, but $40 is too low for me. I'll go up to $65 for it, and won't charge extra for the delivery.
I'll meet you in the middle and pick it up at 52
That'll do fine.
