Also, I'll tell you the trick why Birchbox worked and became hundreds of millions of dollars and why these other box startups aren't in the same game. Birchbox found the best opportunity to capitalize on. They charge subscribers to receive a box of makeup samples. In other words they've convinced people to pay money for ads. The COGS are basically free and on top of that they leverage and poll their subscriber base for data that gets sold right back to the manufacturers. Everyone else is just trying to replicate Sears Roebuck but unable to convincingly explain their value proposition.
