A fair pit boss

Understand how important.  My card can trade with price beacons, using the Amazon secure python and honest pit,  The shoe store owner knows this, I know this.  I can walk the store as he innovates around with new products/  My card and his beacons will trader, strike a deal, no humans involved.  Bots themselves can verify the pit boss as fair. Price elasticity, everywhere, and its automated. And, big bonus, transaction costs assumed zero.
