Do I have to pay monthly for Fire TV Stick?

I have a question about the Fire TV Sticks. At the end of the year I will get a Fire TV Stick to stream Netflix and Disney + on TV. I already have a monthly subscription for both streaming services. Do I still have to pay extra monthly for the stick or does that only apply to the streaming services?

Of course not, the stick is a device that you buy.

No different from a television, microwave, or toaster.

You pay for the stick once. You will only have to pay additional costs if you want to see films from Amazon. Otherwise not.
