And so, Albert Coffee than comes along charging less than the leading supplier. And than Café Brites comes and marks their prices lower than the both of them.
Southern Brewers had to lower prices in order to keep up business. People are more apt to buy low cost idems. So if they wanted to continue being a top supplier, they needed to lower prices.
