Seller: Great.  Are there any questions I can answer for you?
Buyer: What is great about this product compared to the other ones on the market?
Seller: 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.
Buyer: 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?
Seller: I am asking $15 for the headphone set.

[EX Q]: Seller: Hello how are you today?
Buyer: I am doing well. I am interested in your bike you have for sale. I was wondering about the condition, is it road worthy? 
Seller: Hi yes absolutely its road worthy. Maybe the tires might need to be changed in the long run, but otherwise its as great as new
Buyer: In looking at comps, this bike i valued at far less. Because it needs new tires and there is no mention of upgrades, would you take 600? 
Seller: $600 is too too less for what you're getting. I can probably give it to you for $800
Buyer: Could we split difference and go $700? I can come pick up. 
Seller: This is a model of the year 1987 and we know old is always gold. I can sell it for $800 nothing less than that sorry. 
Buyer: I will $800, if you are willing to meet me in a central location that works for both of us. 
Seller: Absolutely we can work that out not a problem on my side!
