What they’re getting at is not applying tax to the price is the standard consistent way to show price in the US. If you have a national ad campaign you wouldn’t be able to show the price with tax because every state and city has their own tax rate. So then, as a consumer, you’d have to guess if you’re looking at a national ad or regional that has tax applied. This also applies to products that have their price printed on the packaging for national distribution. Sure the price could have fine print that says if tax is included or not, but now there’s more than one way to display price — even in a store. See: https://xkcd.com/927
