I've been a prime member since 2001 and it was always a good deal for me because I've literally placed thousands of orders. Plus I send stuff all the time to the parents. Also, I have echo devices all over both houses (at my parents' for safety reasons). Prime music, prime reading...yay, works for me.
And then....
Prime video turned lame, prime music has fewer selections, prime reading is ONLY first in series for indies, Kindle first is 80% crappy books, and I'm ordering less now that they've been outed now for manipulating the search results to show items with more profit...instead of what you might actually want to buy.
Phew....gross.
Of course, with 17 echo devices, I'm now trapped in Prime like a spider's web...so...
