pseudo-currency: items you can trade like cash if the bubble bursts

If the power grid fails for a weekend, dollar bills will always be accepted.  

And I think it's a good idea to keep at least $500 on hand in your home, in $5 and $10 denominations.  

If the stores are open, but their credit card machines are not working, you'll still be fine.

But what happens if things really fall apart?  It's easy to imagine a time when cash will no longer be king.

After looking over what I use regularly, what I have put away for a rainy day, 

& what I think others will also want and need, I've identified the following items as potential pseudo-currency:

- strike anywhere matches

- ammo cartridges

- candles

- calcium hypochlorite

- seeds

- 2 cycle motor oil

- rechargeable batteries

- nails 

- thread, & needles

- cable ties

- candy bars & cigarettes
