Hello I am interested in your item for sale. Can you tell me about it please...
Yes I was given this for Christmas and already have a docking station.  It's like new and in the original packaging.
Alright, since it isn't new, would you be willing to negotiate on the price?
Yes I will sell it for $50.  I can take credit cards.
That is the list price. I was thinking about 40
I'm sorry but I can't go that low.  I will go down to $48 and I can deliver it to you.  It's practically new and could be regifted.
