Hi. I see you are interested in my iphone. It works for Sprint and is in great condition.
Hello! Does it come in its original packaging?
It does not but has been well kept. 
That's not a big deal. So, basically, I will have no problems activating it for Sprint Network, right?
Right. It works only on Sprint. Clean ESN and ready to go.
Okay, I can pay $95 in cash and pick it up from you today. What do you say?
Would you be willing to do full asking cost if I brought it to you?
Sure, that's an even better deal.
