Trump will certainly consider this provocation, so perhaps the news here is that Amazon considered this worth it, even given the inevitable retaliation.
Isn’t Trump the one doing the tariffs? Isn’t the point to get you to buy products without tariffs? I’d think this plays directly into what Trump wants.
The narrative has been that the 'other countries' pay for the tariff. Not the US consumer. So this may be an issue and not one that you can walk away from easily when the customer sees that it is added to their bill.
Trump has at least 3 contradictory goals that he has spoken at length about with his tariff policies so it’s not clear what exactly would make him happy that you could consistently work towards other than I guess capitulating to whatever demands he has that day.
