请教削弱题

A manufacturer of workstations for computer-aided design seeks to increase sales to its most important corporate customers. This strategy is to publish very low list prices for workstations in order to generate interest among the buyers for those ocrporations.

Which of the following, if characteristic of the marketplace, would tend to cause the manufacturer's strategy to fail?

e.buyers for corporations that purchase workstations for computer-aided design receive bonuses for negotiationg large discounts from the list price.

我觉得压价只可以导致manufacturer的利润上不去，不能说明它的sales上不去，只要这strategy让manufacture提高了sales,这strategy就不会fail.所以，我觉得E不能削弱原文。怎么答案会是E呢？

选项E的意思是：企业的采购员会由于成功的讨价还价（获得基于ListPrice的Large Discount）而获得采购企业内部的奖金。

题目是说降低ListPrice，如果选项E的情形成立，那么采购员所能够获得的奖金就减少了，这样一来采购员为了自己的利益就不会考虑采购ListPrice过低的产品，于是降低ListPrice并不能带来Sales增加。

其实，逻辑题难的不是逻辑本身，还是阅读理解。
