Try selling through Amazon.com and see what % you keep.

Then try selling through a grocery or drugstore chain.

The difference being I can always walk to a different grocery store without having to pay ~$1k.

As a brand, do you get more value from being on Amazon or in a local grocery store?

There's still more competition in the retail space and greater ability to sell across multiple stores simultaneously.

Have you tried selling apps trough Amazon or grocery stores?

Sure, but I don't have to sell on Amazon. I can sell through my own website and just pay transaction fees if I want. And many companies do just that now.

But good luck trying to sell your new iphone app through your own website.

At least with android, you could sell an APK download or sell through a different app store.

Considering that Youtube takes 45% of every ad dollar spent on videos I make, I'd consider that a bargain.
