Ad budget for a government monopoly?

WTF? Why does the U.S. Postal Service run ads? It’s a taxpayer funded monopoly, and a poorly run one at that.

So why did I see this ad in a copy of Wired Magazine recently:

U.S. Postal Service ad

Completely unecessary and a symptom of the disease called bloated bureaucracy. A government monopoly does not need to run ads. It makes me angry to see money wasted in this manner.
