Reintermediation occurred due to many new problems associated with the e-commerce disintermediation concept, largely centered on the issues associated with the direct-to-consumers model. The high cost of shipping many small orders, massive customer service issues, and confronting the wrath of disintermediated retailers and supply channel partners all presented real obstacles. Huge resources are required to accommodate presales and postsales issues of individual consumers. Before disintermediation, supply chain middlemen acted as salespeople for the producers. Without them, the producer itself would have to handle procuring those customers. Selling online has its own associated costs: developing quality websites, maintaining product information, and marketing expenses all add up. Finally, limiting a product's availability to Internet channels forces the producer to compete with the rest of the Internet for customers' attention, a space that is becoming increasingly crowded.
