I’d say it’s still pretty far away, and the less digital the business, the further it is. Disregarding laws, regulations, currency status and the level of adoption, and simply focusing on the variability of the price, it’s seemingly difficult to tag prices in BTC/ETH and not lose out.
There are stores that can tag them digitally on the shelf, which makes them changeable throughout the day if necessary, but that is still not that widely spread, and normally expressed in terms of the main country’s currency. Some online sites let you view prices in bitcoin, although most that accept it seem to perform the counter value when performing the check-out (not displaying the prices in bitcoin per se).
