As the transportation and chemical plants slow down. I think that we will be surprised on how the costs and availability of basic items will drastically change. That has been said in a whole bunch of different ways, but the truth of the matter is, we currently have no inkling how bad it will be. I am hoping that the losses won't be too severe and will be manageable, but if I had to place my bet, I would bet that the shortages and cost will drive us crazy.
Consider shaving. Now, I like a beard in the winter, but in the summer, they are hot and scratchy. So a razor is somewhat essential, I can live without it, but would prefer not doing so. But the razor's nowadays come from one or two companies back east (Schick or Gillette), or are electrics. If the availability or prices of these items change drastically, you are currently beholden to a company for an essential. You might want to try to locate a straight razor.

Soap is going to be an issue, when you look at it, soap has the same trend as razors, a couple of manufacturers, a couple of plants, the majority of the country beholden on a few. Not a stable system. You might want to make nice with your local hippie-type. They always seem to know folks who make their own soap. You can probably even get stuff that you prefer.

I am not going to run it down product type by product type, but I think that you get the point here. I don't know about you guys, but I like being clean and wearing clean clothes and general sanitation. This is a great thing. Make sure that you have a means of maintaining your cleanliness and health in the changes that are coming.
