Because supermarkets serve as the link between supply and demand, they are the most significant part of food production and delivery. Farmers markets are an option, but they are out of reach. As a result, when a retailer like WalMart decides to sell milk made without particular hormones, the entire milk production sector changes. The competitive advantage of a farmer is no longer "produces more milk," but rather "produces rBST-free milk." In a similar spirit, supermarkets and farmers markets are ostensibly competitors. Shop at farmers markets, and supermarkets will begin to seek out and sell organic items that are only available at the farmer's market. Supermarkets are necessary for today's lifestyle. Today, finding the ingredients you need to create cuisine in mom and pop specialized stores and butcher shops is difficult. Because supermarkets may buy in large quantities due to the ease of 'one-stop shopping.' They may buy things for a cheap price and sell them for less than a tiny, mom and pop business would pay for the same goods. And drive tiny businesses out of business. As a result, we now have to go to the grocery to acquire what we need to make our meals.
