Hello, can I help you?
I love this watch, how much are you seeking for it?
I have it listed at 185, but am flexible. What are you thinking?
Unfortunately it is used, so I do not want to pay the full $185. Can you come down on your price?
Start making me a price range and I'll tell you what I'm thinking.
Would you be willing to do $75? If I wanted to pay $185, I'd buy it new from the Apple Store!
