人們買高級名牌貨是因為牌子.因為這些名牌貨不是每個人都有.這些人喜歡別人買比較特別的東西.但大量行銷的手法還有低價賣的方法.不能用在這些商品和這些人身上. 題目是問, 為什麼兩種手法不能用.....
B. 這樣的行銷不能用是因為高級產品賣的它是稀少和特別.

這是我自己的解釋.希望幫的上忙. 一定還有更好的解釋.

continued sales depend directly on the maintenance of an aura of exclusivity    持续的销量必须依存于对（奢侈品）的排他性的特性的保持
换言之就是，奢侈品的亮点就在排他性，人人都买得起，就没这个特性了，反而原来的消费群就不会买了，买了就=自掉身价
