If the manufacturer follows suit, then under the principle of "price protection" which is usual commercial practice in America, distributors are sure to ask for a refund on goods they have already bought at the higher price; and if the price is below that paid by the US subsidiary to the Taiwan parent company, the subsidiary too will have to turn around and ask for payment from Taiwan.
劉萍提出質疑：如果跟進，依美國業界「價格保護」的慣例，通路商已經用高價買去的貨品，一定會要求原廠做價格補貼；甚至新價格若低於美國子公司向台灣母公司進貨價格的話，美國子公司也必須回過頭向台灣算帳，可謂牽一髮動全身。
