If you’re going to make a website where you sell stuff, it really, really helps to make clear what currency you’re displaying your prices in. Especially if you’re not even based in a dollar-using country, but you display all your prices with a simple dollar sign. Then I have to make a guess whether your site is localised, so you mean AUD, or whether your European or whatever company just charges everyone in USD despite that making no sense. (You would think the former, but the latter is the case like 90% of the time.) Just three letters and potential customers could actually know what your prices are, how radical ✨
