Manufacturers sometimes discount the price of a product to retailers for a promotion period when the product is advertised to consumers. Such promotions often result in a dramatic increase in amount of product sold by the manufacturers to retailers. Nevertheless, the manufacturers could often make more profit by not holding the promotions.
Which of the following, if true, most strongly supports the claim above about the manufacturers' profit?
(A) The amount of discount generally offered by manufacturers to retailers is carefully calculated to represent the minimum needed to draw consumers' attention to the product.
(B) For many consumer products the period of advertising discounted prices to consumers is about a week, not sufficiently long for consumers to become used to the sale price.
(C) For products that are not newly introduced, the purpose of such promotions is to keep the products in the minds of consumers and to attract consumers who are currently using competing products.
(D) During such a promotion retailers tend to accumulate in their warehouses inventory bought at discount; they then sell much of it later at their regular price.
(E) If a manufacturer falls to offer such promotions but its competitor offers them, that competitor will tend to attract consumers away from the manufacturer's product.

D) (D) During such a promotion retailers tend to accumulate in their warehouses inventory bought at discount; they then sell much of it later at their regular price. - This answer proves that manufacturers could sell more product at a higher price because the retailers are making the excess profit.
Now let's a manufacturer has a promotion and the retailer sells at fair value. They would normally sell at $5 but sold at $3. Therefore the manufacturer lost $2 of sales. E is actually quite similar to D for the overall industry. D is more tempting but E to me has equal weight.
(E) If a manufacturer falls to offer such promotions but its competitor offers them, that competitor will tend to attract consumers away from the manufacturer's product.
See the questions asks about Manufacturers not Manufacturer's. Meaning we should be looking at the industry as a whole. The argument in E doesn't say we increase customers. Therefore E & D would both show that the industry as a whole loses. Let's do a quick example. Product normally is $5 a deal makes it $3. So company A doesn't sell for $5 and company B gets the sale for $3. Therefore $2 in potential industry sales were lost due to the promotion.
I guess D is a little stronger considering it shows the promotions are mainly benefiting the retailer not the manufacturer. But E is not being properly assessed by people responding in this forum.
