I think better customer satisfaction, more efficient inventory management, cutting third party supply chains, and higher profit margins are few more reasons.

In light of recent media reports following December (Christmas) sales, I would suggest returns could have a significant impact on profitability.

The most important point in DTC is the ability to build the brand relationship with the customer. This is vital as influencing the 1st customer to buy from a specific brand is challenging while retain and influence your customer to return and purchase again is even more difficult. Thus brand loyalty is an imperative part for big companies. DTC allows the company to transmit their brand’s story more effectively and relay their message more directly and potently to connect with consumers in a deeper level ensuring brand loyalty to generate a continuous revenue.

Question seems odd to me. Direct to consumer is a critical channel. For many companies, it's the primary channel. For everyone else, your ability to understand it may be the key to success.
