What's insane about this is the streamers are getting to the point where their annual pricing is as much as all of Prime, and you only get their shows and movies. Prime you get originals and movies and shows outside of those and all the other perks of Prime.
YMMV. For me, I ended up doing the opposite of what you posted. I quit Amazon Prime, and went with other streaming services. For me, there just wasn't any value in Amazon Prime anymore. Their 3 "areas" for me fall under...
1) Prime shipping
2) Prime Video
3) other perks
For #1, I've cut back over the years where I'm down to buying from them to about once per year. They used to have nice discounts, but a lot of things used to be discounted, say, 20% to 10% off, are now sold at MSRP. I need to go out anyways, so may as well stop by at a brick & mortar store, and pick it up, the same day. I buy so little from them (about once per year) that I can either just combine shipping, or it's better to just pay shipping out-of-pocket. As for orders taking longer, non-Prime shipping is only a few days more.
For #2, I have a few shows I'd like to return and catch up on, but I'll do so a la carte. Subbing to Prime Video (just the streaming service) for $9/mo (and add $3/mo for ad-free). However, there's also a lot of great content on the other ss (streaming services), so it can take a while before I rotate back to this. With Prime Video, much of the stuff required extra money b/c you need to buy/rent it a la carte, or sub to
yet another streaming service (like Hulu, or HBO Max). When you filter all of that out, there's not much left. Amazon Prime can subsidize their streaming with their other businesses. The other ss only focus on streaming, which to me, has yielded much better content.
For #3, these are nearly all worthless to me. Prime Music, Photos, Whole Foods, pharmacy/drugs, Twitch Prime, etc.... I tried to get into these but they mostly just don't apply (for example, I don't live near a Whole Foods). I did redeem some in-app purchases for a video game so I got $10 value out of that, but that's about it. In fact, other countries only pay $50 to $80/yr for Amazon Prime b/c they don't get any of these "other perks". I wish we had that option :\ And others in USA are wishing they could just pay for Prime shipping because that's all they care about)
... Quitting Amazon Prime put $150/yr (after sales tax) back into my pocket. I used those savings towards a dedicated ss, and it's been great!
