Participate in a discussion regarding monopolistic competition you encounter as shown in Section 17.3 in the textbook. Almost everything you buy includes a selling cost component that exceeds one-half of the total costs. Your clothing, food, DVD's, and your textbook for this course cost more to sell than they cost to produce.

Why are selling costs so high? In other words, what is "bundled in" to the cost of your product beyond profit, labor, transport, and raw materials? In your response, consider what firms must do to differentiate their product from others on the market, starting with product conception and ending in consumer purchase.
