Seller: Warranty is still good. Asking $595 for it.
Buyer: Would you accept $297 for it?

Buyer: I'm sorry. How about $400?
Seller: That is still really low. Like the listing says, the price is really good where it is and I wasn't intending to take any lower offers on it.
Buyer: How about $515 and I'll come pick the phone up from you?
Seller: If you can pick it up right away and pay cash I can do $515
