I think as with Uber and Airbnb, drop shipping is a service that will soon become the norm as more and more people express their comfort in its use. The obvious challenge is finding someone that you trust to partner with. Customer support is the key factor that will separate the legit drop shipping services with the pretenders. It's not enough just to function as a website, ecommerce owners want someone they can develop a personal working relationship with that customizes to their needs.
