Hello, you still have the beats? 
Yes. interested?
I am. Are you willing to accept $122 for them?
They're pretty high demand. I might go as low as 160.
How about $150 and I pick them up and pay in cash today? 
If you can pay 155 you have a deal.
You're pulling out of my gas money! $153 and it's a deal. i need gas to get there. 
You drive a hard bargain. Okay then 153 it is.
