I simply just reply with the same question. What’s the lowest you’ll take? I say what’s the highest you’ll pay? What’s your best price? I say what’s your best offer? If they say $100 cash right now on an item I have for $150, I ask how they plan to pay the remaining $50. Now if someone comes in and tries to negotiate like a human, then I’ll play, but these jackasses that think they will knock my price down by playing “hardball” can get fucked.
