We shop no more than once a week, so we save on gas and don't buy prepared foods, snacks, or soda. Basically, we buy the least expensive good food we can afford which at the moment is not much. FYI, one of the local grocery stores has turkey for .48 per pound. If we had the freezer space, we would have bought several as that is cheap eating. We do eat well and are not going hungry.
All that is gold does not glitter,
Not all those who wander are lost
The old that is strong does not wither,
Deep roots are not reached by frost.
