Individual situations may vary. I stock some food. But I live in an apartment, so there is only so much space. Also, I like tasty stuff. I end up throwing out a lot of canned goods that cannot compete with their fresh counterpart.

Contrary to all the sites and posters that tell you to buy MREs or whatever, I learned here to stock stuff that I can stomach even in an emergency, because you don't want to be eating stuff you are not used to and you don't like when you are feeling miserable already. Another example of why ETS is a good site!
