原始寂静 A local bookstore "Food for Thought" is specializing in cooking related books and has an in-store cooking demonstration. The owner recommends that the store offer discounted best sellers (at no profit) to attract even more customers and beat competition because major bookstore chains and Internet store have used the strategy successfully. To offset the cost associated with the deep discount, the author also suggests discontinue the cooking demonstration. As a result, the sales volume and profits will be increased.
