Seller: Nope! It has a minor scuff by the charging port. This does not affect its charging abilities and it can barely be seen
Buyer: I see it is silver is that correct??
Seller: Yep! Would you like to make me an offer? I am happy to negotiate near the listing price.
Buyer: I could offer you 325 for it, I could bring you the cash today.
Seller: Unfortunately, that offer is too low. Can you do $415 and I will include the case and a pair of headphones? I can pick it up from you. 
Buyer: That would be fine since you are including the case and headphones and bringing it to me. Thanks you got a deal.
Seller: Great - So to finalize... it will be $415 for the phone, headphones, and case. I will bring it to you.
