PC Burn-In: IEC Adaptor from Radio Shack?

Someone here stated Radio Shack carries an IEC to wall receptacle converter. I searched forums, but couldn't find the thread.

I can't find it Shack on line and Cust Service knows nothing.

Sidenote: Do Power Cords really need that much burn in? They don't carry signal, so dielectric burn in may not be an issue.
