Ok, what's a wall wart? That's the little box that you plug in to operate your electric powered dodad. The box plugs into the 12" long tail which plugs into the recepticle.

A normal six slot power bar will only hold two wall warts. By adding the tails, you can plug in more boxes to power more dodad's.

I had these cords manufactured to my specifications. This quality cord will handle 15 amps of current with no problem.  

The pictures tell the story.

$5.00 handling plus actual shipping charges. Multiple quantities will only have one $2.00 handling charge for all of them. Add 3% for credit card purchases. The price is for one bundle.
