Input (English): Seller: Good morning. Are you interested in the iPhone 6S I have for sale?
Buyer: Wow that seems to be a great deal. But i am just curious do you have your Dad's permission to sell the Phone
Seller: Absolutely I do. He's not very tech savvy, so he asked me to sell it for him. Like I said in the listing, it's in excellent condition, with only a scuff near the charging port (probably from him trying to plug it in in the dark, haha). We're looking to sell it for $450, but I'm willing to negotiate on the price.
Buyer: I see. Do you have the Phone accessories too such as the Charger and headphone for the Phone?
Seller: No, but I am throwing in an Otterbox Defender case, which is worth around $20.
Buyer: I see. I am willing to offer $300
Seller: My dad won't accept that price, but I'm willing to go as low as $360 if you purchase it today.
Buyer: No charger, No head Phone. I guess i will spend up to $30 to get those. $320 will be ideal. What about $320 then
Seller: I can do $320. I'll send you an official offer for that price.
