Hi! I am very interested in buying this Headphone set!
Great.  Are there any questions I can answer for you?
What is great about this product compared to the other ones on the market?
This product is new, fits both iPhone and/or Samsung.  It is very attractive and it has it's own carrying hard case for storage.
Ok awesome. I would like to purchase the item and I am willing to pick it up. What is the best deal that you can offer me?
I am asking $15 for the headphone set.
I understand that but I am willing to do all the labor so you do not have to pay for gas or shipping. Would you be willing to go down to 9 dollars?
Nine is a little low.  I would go $12.
$11 and you have a deal!
Okay -- great!  $11 it is.  Thank you.
