Hello
Good afternoon. Are you interested in the Lumia I have for sale?
As stated in the listing, the screen is cracked, but it is in perfect working condition otherwise. I've lowered the price to $60 and the cost of getting the screen fixed isn't expensive.
Hello, I think we may have our lines crossed... I am interested in the Nokia for sale.
Yes. It is a Nokia Lumia, as stated in the listing. I'm willing to negotiate on the price. 
Ok, I think I was getting parts of another conversation.
No, I talked about the crack on the screen, which is clearly stated in the listing. Do you have an offer on the price?
Yeah, considering the screen is cracked I would want to go a bit lower, would you consider $50?
I accept your offer of $50 if you can pick it up today.
Ok that sounds great, thanks.
