No, that's not the same thing. Tariffs are taxes collected by customs agents (no matter how much this administration wants to pretend they aren't), and taxes already show up as itemized additions to your receipt, unlike margins and seller fees.
To me that just means they're already doing selective transparency. They treat government influences on price as different than other factors that influence the price.
Every receipt I’ve ever gotten in my life has separated tax, and I don’t recall I’ve ever seen seller margins or anything like that on a receipt before.
Yeah, I'm not saying Amazon is the only one doing this. But I am saying that if they're saying that consumers deserve transparency, this just scratches the surface.
