Hi! Are you interested in my iPhone holder?
I would love it! It looks great!
I have it listed for $35
Thats not too bad, but is it new? 
It's not, but it's in great condition. I bought a new one when I got a new phone.
Thats great, but how about 20 dollars since its not new? 
I paid $100 for it. Could you do $30?
Sure! Can you send it to me?
