If one business excludes tax from the price while every other business includes it, that’s misleading advertisement. I think writing the full price to be paid by the customer should be mandated by law, in which case no business gets a relative advantage over any other. Where I live, we go even further: if you offer a subscription with a binding period, you also have to write the minimum total amount to be paid by the customer before they can cancel the subscription. This helps prevent customers into getting tricked into spending more money than they can really afford, which is a good thing?
