Hey there! Are you interested in my Iphone 6 64GB? It's Matte Black color. Like new, barely used.
I really need a new iphone to replace mine. I am quite interested. how old is it?
Its only a few months old but I didn't use it at all really. I'm selling it for around $320.
Its look like its in good condition. I would be willing to pay around $280 for it
Okay I can do $280 if you can stop by my place and pick it up. 
sure. I can definitely pick it up and I will pay cash
