I would love to have the phone. I can give you 82 for it
I'd feel a bit better if you could do 85. Is that possible? It's unlocked and in good condition.
I can do it for 85 if you can give me the charger and case. 
That's not a problem. 85 with the charger and case.  It's a deal.  I can meet you at the AT&T store if you'd like.
