I still shop at some grocery stores (regrettably even Wal Mart... I guess someone's got to help China to keep the whole debt shell game afloat LOL)

We have a huge barter economy that will likely flourish as the dollar and social order rots or collapses. Barter could be anything for anything.... Craigs list has been a freaking awesome local economy engine as well.

We also grow what we need... be it on the tree or on the hoof or out of the garden.... heirloom seeds all the way!!!
