Earlier quoted context omitted.
I pay Australian GST on AliExpress imports, but it doesn't make local outfits more viable. I buy hobby electronic components primarily, local suppliers are often one to two orders of magnitude more expensive, not just a few percent more.
One or two orders of magnitude? Isn't that ten-times or a hundred-times more expensive? What product could possibly be marked up by 100x?
CR2032 batteries are a common item with an order of magnitude markup (20c each vs multiple dollars here).
