Amazon ripoff with children

I would like to make time to briefly air about how Amazon jumps here at children content with its customers. Last week is part of Prime Instant Video, first at no additional cost. 12000 contents are there flat to retrieve available, including all the seasons of Bob the Builder. Our son is very enthusiastic and looking in recent days repeatedly consequences to. And then we can see today that from one moment to the next all the contents of Bob the Builder are suddenly no longer part of the Instant Video / Prime subscription model, but must be paid for separately. I see that as a real sneaky rip off in the form of "we entice children ran to the content and then the pay-Wall snaps". So what I knew not from Amazon before. But for us it is clear that we will finish our consumption of instant video after a week. Since we prefer to book for 7,99 EUR max cathedrals or something like that and then really "flat" content for children, who also remains so.
Ugh, Amazon!
