One of the best ideas I have ever heard of.   

If you buy a $3,000-plus solar power system from Bland Solar, they'll throw in a gun for free. Hilariously promotional juxtaposition? Sure! But it also makes perfect sense.

See, here's how I figure it. When the grid collapses and traditional fuel sources have been exhausted—sometime around 2012, say—you're going to need two things: solar power to keep your domicile running, and a sidearm to stave off the mutant hordes.

The gun comes in the form of a $400 gift certificate, good towards the purchase of a gun, rifle, or ammunition. I say go for the rifle. You'll want a little more reach when the bullets run out. [Consumerist]
