I've stopped shopping on Amazon entirely, and the impact on my credit card bill has been substantial.
It's not simply that products are priced poorly, but it is also that they seem to be priced just at the threshold where the purchase remains sufficiently convenient not to shop locally or elsewhere online.
Because of their predatory practices it seems online prices are roughly identical for Western branded products at all online retailers. For Chinese brands, it's long been cheaper to use AliExpress but shipping isn't as fast and returns aren't as convenient.
But that's perception. I blocked Amazon and continued shopping as usual. The volume of my purchases is now through local retailers, and I'm buying roughly the same amount of stuff but I'm spending a great deal less.
