Market Share in Our Life

Market Share in Our Life
In our daily life, there are many famous brands around us, and in a same field, there are also few famous brands, they have the market share almost equally, because of this situation, I believe the market share offer a variable choice to our life, if there are more pieces of market share. And the variable choice offer many chance to save many, at the same time we can get more goods.
For example, in Marietta there are several pharmacies, if I want to buy a bulb, I will to go to each pharmacy, and try to find the cheapest one. Another reason is that there is a competition between each pharmacy, so the price of goods will be fine and cheap. There are more pharmacies means there are more goods to sell. Because each pharmacy is different, each one has its feature, so they can offer different goods and we can buy more goods than there is less pharmacy.
