Many producers do not sell directly to their ultimate consumers. The producer of a consumer good may, for example, sell it to a wholesaler who will resell it to a retailer who in turn will resell it to the ultimate consumer, and even if there is no wholesale stage of distribution, the ultimate consumer will ordinarily be the direct purchaser from a retailer and only an "indirect purchaser" from the producer.
