The best deal I've found for storing water is 2.5 gallon containers of spring water, $1.00 per container. That is cheaper even than buying 5-gallon jugs in my area. The added benefit is that the 2.5 gallon size fits easily in the refrigerator so we are constantly rotating stock. Although packaged water is supposed to have a long life (indefinite, according to the FDA), it is still worth rotating.

Cheaper still is storing your own tap water. But this can be dicey depending on the source, treatment method and residual contaminants. Also, empty bulk containers tent to cost more than filled containers from the store, and don't fit in my fridge (at least not unless I take out all the beer ;^P )

And as for the Jeep, pics or it ain't true.
