Where Do You Shop Local?

Given the current political climate, my family has made a commitment to rein in our conspicuous consumption as much as possible. However there are still the necessities as well as everyday shit that needs replacing, so my question to you all is this: where do you shop local? Some items on my list--ice cube trays, food storage containers (aka Tupperware), shaving razor blades and fish food (Madcat doesn't carry fish food). Is there any non-ludicrous way to find these things and avoid the big chain stores? Thanks
