I did the math for me and even with the Amazon credit card the service wasn’t worth the price. It’s free shipping over ~$25(?) dollars anyway. “Prime shipping” hasn’t meant anything significant since at least 2020. It’s often the same as non-prime, maybe a day earlier.

If you care about the shows that maybe changes, but they have about 5 and anytime you search for something it’s a tossup whether it will be included with your subscription or only available for buy/rent or on some other platform. It’s even more fun when there’s ‘copy’ of a movie included with Prime, and another available for buy/rent and and buy/rent version is at the top of the search results and the one you already paid for access to you have to scroll to see.
