I am a bit confused on the app purchase.
I see the Renting movies within an app question below.

Looking around I found this thread
http://stackoverflow.com/questions/16545238/apple-in-app-purchase-alternative
I see apple's guidelines
https://developer.apple.com/in-app-purchase/
https://developer.apple.com/app-store/review/guidelines/#purchasing-currencies
I guess my main question is,
Do apps like Amazon, Uber, etc... all pay a 30% fee when selling in the apple universe?
I cannot imagine that Amazon will pay that fee. Or do they?
thanks for any insight
