This means grocery stores are your suppliers. We are lucky to have so many competing grocery store chains (at least in any major US cities) for the best supplier for the INGREDIENTS, and that means you could have a bunch of grocery stores for any of the ingredients to choose from based on their quality, selection and price.

Don’t forget, you don’t owe the store anything other than your patronage on the great ingredient the grocery store is providing (where one doesn’t fill the shoes, others will), In time, you would find a match or two that would fit your criteria, few examples below: 

At times, you may need an ingredient that is different based on fresh or frozen, like many types of seafood, for example: fresh salmon vs frozen salmon. As many of you know the result of baking the salmon is different based on the selection: fresh would be juicy and tender (if baked just right past the safe internal temperature) and frozen would tend to be more stiff and dry with the same cooking method.  

As you would, if you are running a restaurant, sustainability is what keeps you in business. This is no different at home, even with differences in household income, there are always deals from grocery stores from one to another which you would find to have great groceries with the right price, just do your homework and you will save!
