If buying something (anything - pencils, stickers, gumballs, etc, etc) from Amazon, the process should be preceded by a query to Ask Rufus:
Ask Rufus: "What is the tariff cost increase for this product?"
Better yet, do it for products you don't end up buying also...
"Lost sale? Well maybe this is something we should address?"

Trend it until you make it.
