Hi is the bike still available?
Hi, are you interested in this bike? Yes, it is still available. 
Yes I am. So are you only getting rid of it because it is too small for you? No other issues?
Yes. It is in great condition still and I barely used it. 
but it was used when you bought it off craigslist, correct?
I bought it new
hmm, seems weird to have new of cl but ok..
Yes. I am selling it for 170
I am really on a tight budget and was hoping you would come down closer to $118
How bout 125? That seems fair to me.
Can you deliver ?
Yes, but then it will be 130.
I will pick it up for 120?
Sure. That can work.
great
Good doing business with you.
