Proof I'm not as smart as I think I am: I swear I spend at least $400 a year on shipping but I keep refusing to sign up for Prime.
The deal on the shipping is this:
If you notice, Amazon sells things through Amazon (that's where you get the "prime" free shipping), plus through third party sellers. The prices from the sellers plus shipping will equal the Prime amount. So you don't get free shipping with Prime. The price of the item is increased to include the shipping cost.
Without Prime, I could buy the item from a third party seller and pay shipping, and end up costing me the same as buying it through Prime from Amazon.
There may be some items with Prime that don't have third party sellers, though. I don't know. And it is convenient to order directly from Amazon.
The Prime video is sub-par, IMO. It's built on the business plan of trying to sell you Amazon stuff....if you want Season 2, you have to pay per episode or buy the DVD. I don't like its original programming as much as Netflix's. Still, occasionally I watch something for free on Amazon Prime Video that I can't find elsewhere, like the tv series "That Girl" or "Dead Like Me."
Amazon Prime and Netflix are not live tv like Sling, Pluto, and other services. The Amazon & Netflix services are videos. The others have channels and are like tv.
There is a comparison online of the various live tv experience services available. Sling, Playstation Vue, etc.
I have a Roku. I get thousands of free stations (video stations like Crackle, TubiTV), and a few live tv channels (which don't work great, but are okay). It has a station for Playstation Vue now, I think. It has a station for SlingTV, once you subscribe. Roku is awesome and the #1 streaming device. Youtube is on it, too.
I just looked up Youtube TV. It's $35/month. Yikes! Uber expensive! Not for me.
Slingtv -base plan is $20/month. Higher plan is $25/month. Add-ons @ $5 each.
PlutoTV (not very good but has some unique stuff) - free
Playstation Vue - not sure of the cost (you don't need a Playstation to use it)
