I don’t see this hurting Netflix. I subscribe to both, but for very different reasons. Netflix is my main streaming service by far, while Prime is used for the free shipping (which is used all the time).
The monthly cost is Prime is more than the annual cost. What would be good is if Netflix had an annual option that was cheaper than monthly, since I would buy that.
Bosch is the one Amazon original that I do enjoy.
It gives those unable to come up with $99 at one time an option.
