I'm not seeing the issue with this. I read through all the replies up to now, and it appears to me that people are complaining about services they're taking for granted.
I live next to a major us city. Chicago to be specific. I order lots of things, and they get delivered very quickly. I do not have problems with prime shipments taking 4 or 5 days like a couple peoe complained about, but didn't say where they live. I purchased prime solely for the shipping bonuses.
People are complaining about shipping and comparing it to super saver, but the last time I looked there is a minimum purchase price for free super saver. With prime I can buy a single item that costs $4 and have it shipped, and I get it in a couple days. I do not have to store my purchases in a shopping cart until I have enough to qualify. The immediate shipping is the single biggest benefit.
I also cut the TV cable cord last year. I now do Netflix and prime plus plex and that's it. I use roku, and it works great! Many of the movies I could watch on amazon are also available on Netflix which is my primary TV platform, so I rarely watch stream from amazon. But comparing Netflix to amazon is not relevant. Compare amazon prime streaming to not having any streaming, and you'll see that this is a pretty huge benefit that is thrown in with the faster shipping I paid for.
I have three kindles, but I have never used their kindle book services. Maybe some of the books I read are available there, but they're also available in other places including my public library which has a method to check out kindle books.
I get no benefit from amazon music, but its fairly new and I can't hold that against them.
The original article makes it sound like people that were sharing amazon prime membership with friends are getting screwed. So what? It can be shared within a household, meaning whatever your definition of family is. If you cannot share a credit card, you're probably not family. You're basically abusing amazon prime services, and shouldn't be sharing an account.
I don't see an issue with amazon clamping down on people that are unrelated and shouldn't have been sharing a single account, and I think they provide a pretty decent value for the money. Maybe it's not a fantastic value if you only buy big ticket items that get free shipping anyway and don't use any of their streaming services, but it is a pretty good value for those of us that only buy one or two small things at a time, whenever we think about it night or day multiple times a week. We get prompt, free (prepaid) shipping on our small purchases and its awesome!
