What do you think would happen if the opposite occurred? 2. In your opinion, has the rise of e-commerce and online purchasing increased growth in the economy? In what other ways has e-commerce affected the economy? 3. There is a plethora of dollar stores" that purchase the oversupply of many manufacturers and sell it at a dis- count.
