Arbitrage? Please explain...

[NPKJB]

Can someone please explain what arbitrage is in the domain business?
I hear it kicked around a lot in the Parking & Traffic Monetization section.

Thanks!!

It pretty much means you can't purchase traffic to your parking domains to make more money from PPC.

PPC arbitrage is the practice of buying traffic and promptly reselling the same traffic for a larger price. You keep the difference.
