OK, I found out my daughter could and did set me up under her Student Prime Account.
But then I could not access any videos, I kept getting a 30day free trial message on the video I selected.
I find Amazon has an 800 help number, I called that, I got help removing the two I items I accidentally clicked on and bought. A friend warned me about that, but I had just started using the Firestick remote and wasn't used to the buttons. I had to get a little stern with the agent, he said it's only $0.99, No, I don't want it, you can try it for a month and see, NO, I don't want it.
Ok so they took care of both items, but each had it own department and wait time.
They could not understand my third problem with not being able to access videos, I think do to language difficulty.
Then I tried the chat, After some time I found out that as a member of a student paid household I was not allowed free Prime Video, only free shipping.
So, I signed up and paid the $99.
I can now access the videos, and like the interface very much. I'm also adding other video streams to the Firestick.
My daughter was already looking forward to me paying her student prime bill when it came due in February, she quickly shifted to getting in on my Prime as a Household.
I was being Mustachian getting on her account, she's just sponging off dad, getting on mine.
Right? :-)
