The key to prepping is to be ready for all eventualities. It's not enough to have stock piles of food and water. At some point you'll need to barter!!
That's where silver comes in. It's currently incredibly cheap and readily available at the moment so stock up on a few ounces, because you'll be surprised at how much it may end up getting you.
I first got the silver bug a few months back and picked up a few ounces. I had saved up some fiat and went to my local supplier to pick up some more Brittannias.
AND THIS IS WHAT I LEFT WITH:
The complete run of 1oz britannias. I Spent far more than I wanted to but still feel I had a great deal and could sell them tomorrow and make a profit.
