I've made the comment many times, by the time you've paid for a service like this, Netflix, Amazon Prime and an internet connection fast enough to handle multiple HD stream simultaneously, it would have been cheaper to just have a internet and TV bundle.
This is even more true when the cable companies start jacking up the pricing on internet only connections to offset the loss of revenue on the TV business...
This is true, all the individual plans can add up quickly, but I think a large percentage of cord cutters don't pay for every service, even though they have access to all of them.....
Many will only pay for 1 of these services while utilizing / sharing accounts with family members, friends, etc. for all the others.
Their cost (vs cable / bundle) can be significantly lower, while still getting all this content.
