Hi I am interewted in your unlocked Iphone 4 you have selling for $80. Can you tell me some basic fact about it?
Sure. I have only used the phone for about a month. I decided I wanted a different color, so I got an new phone and I am selling this one.  It works great.  Are you interested?
Yes, I am interseted. I will pay $72 for it because I do not think it is worth $80. Is that good?
If you can pay $80 I will also give you headphones and some bluetooth speakers.  Do we have a deal for $80?
