求助，这句话怎么翻译啊， Nor do price promotions have lingering aftereffects for a brand, ev

Extensive research has shown that the effects of short-term price promotions on sales are themselves short-term.  Companies’ hopes that promotions might have a positive aftereffect have not been borne out for reasons that researchers have been able to identify.  A price promotion entices only a brand’s long-term or “loyal” customers; people seldom buy an unfamiliar brand merely because the price is reduced.  They simply avoid paying more than they have to when one of their customary brands is temporarily available at a reduced price.  A price promotion does not increase the number of long-term customers of a brand, as it attracts virtually no new customers in the first place. Nor do price promotions have lingering aftereffects for a brand, even negative ones such as damage to a brand’s reputation or erosion of customer loyalty, as is often feared.

最后一句话。Nor do price promotions have lingering aftereffects for a brand, even negative ones such as damage to a brand’s reputation or erosion of customer loyalty, as is often feared.

nor的否定是指必须在一个否定的环境中，也就是他前面的部分必须出现否定词，但它的意思还是表示＂也＂。就像too一样，但是too必须用在肯定的环境中。
