That's the point. Indeed, it's nearly a 100% marketing success. Just because you CAN buy the same razors another way, doesn't mean that any normal consumers do.

As another HN post pointed out, DSC was able to combine existing tools like AWS, Facebook, YouTube to build a $250MM business in a matter of years, exceed $1M in revenue per employee, and sell it for $1B. A decade ago, this would have been completely unheard-of -- think how much you'd have to have spent on building your own tech stack, display/print/TV/direct mail advertising, phone operators, etc.
