It was already too expensive to get anything sent from America, so this will be the final nail in the coffin for a lot of overseas buyers and small US businesses are about to lose a lot of overseas customers. I don't think American small business owners realise that a lot of their online sales come from foreigners. Well at least it was 10 years ago, before they started over charging.
A lot of American products are poorly made anyway, so I avoid them if I can (I mean, Australian products are poorly made too for the most part)
For all the shit China gets for exporting 'cheap and nasty' products, if you're not shopping from Temu or something most of the time it's either same or better quality than American or Australian made stuff.
