Most of the manufactured items on Amazon are just white label products from Alibaba, and you can buy them cheaper on AliExpress.
Only times I’m using amazon is for cheap items no one else will ship. They’ve really just turned into AliExpress.
And don't forget, Apple was also doing shady stuff: https://www.theverge.com/2020/9/3/21419729/apple-california-...
For a quick and concrete example of this, do a search on Amazon for "dent puller". You'll get pages and pages of obviously identical suction cups and dent removal kits with obviously randomly generated brand names like "LTGABA" and "QGMZZMF".
It really drives the point home that you're paying premiums to unnecessary middlemen by buying on Amazon.
I've been impressed with what sellers on Etsy offer when it comes to things that can't be found through AliExpress or domestic retailers.
