Read about the 7 perks
If you're an Amazon Prime member: Did you know about the 7 perks? (If so, which one/ones)
I canned Prime years ago because it didn't feel like good value for money.
Free delivery is great, until you realise how much you're actually paying for it.
I found Prime TV to be of very limited value. The number of times I'd activate my Fire Stick to watch something of an evening only to find the things I wanted to watch weren't actually included and required further payment (either to rent or buy from Amazon, or only available on another service). Needless to say Amazon couldn't have marked them from the main screen, I guess they hoped you'd click them and simply put up the cash rather than grunting in annoyance and hitting the Back button. Most of what was available to watch was either available on Netflix, or not worth the subscription cost.
Prime Music is great in theory but I'm not really interested in streaming music. I'd rather have it on a local device so I'm not chewing through mobile data, or using up bandwidth at home. Now I've got a much faster connection but don't want to deal with advertising mixed in with my music. If I wanted that I'd just turn on the radio.
Kindle Unlimited is great in theory but in practise never really offered books I was interested in reading. I prefer physical books anyway, there's something about physically turning pages that you just don't get with a tablet. I used a Kindle for years, mostly when I travelled a lot, but the main benefits of not having to carry physical books kinda fade when you can stack as many as you want on the coffee table.
Now so much of Amazon's main site is third-party vendors with unpronounceable names that insist you won't regret buying from them, all in badly broken English. "We at HGHEUFK are devoted to you satisfy, if you have problem just out reach HGHEUFK and we make everything good. You'll be glad bought HGHEUFK".
