I buy a few. WINCO Foods in Western U. S. has a large bulk section and I do purchase some things there. But honestly I don't buy anything in bulk that won't be cooked. I had someone give me a snarky reply of "you buy produce don't you" when I stated such on a vegetarian website I went to. Someone had posted about an all bulk store opening some place. Probably in an urban area. I can wash produce at least but I can't wash a corn flake or piece of granola. I actually almost envy people I see buying this stuff without seemingly a worry about it. I just won't. Food contamination can happen at every level but I have seen people stick their hands into bulk. The ones that empty out the top into a bag are a little cleaner but I still buy only things that will be cooked like oatmeal, nutritional yeast, dry refried beans (a favorite) etc.
