I just wished it was mandated to list prices to include all the taxes along with it. Whether it says $19.99 or $20 still isn't the actual price.
Recently had the worst of this. Was craving chocolate milk, find a nice size bottle of it for $3. Get to register. $6.63 total price because the glass bottle had over a $3 deposit.
If I had to guess its probably because the stste was kinda in a weird place when digital products were first becoming a thing so it was never implemented, and now nobody cares enough to try.
Yeah, and? That doesn't stop the individual stores from already calculating the taxes you're going to pay at that location and putting that price on the labels on their own shelves.
Then leave the advertisement alone. They still print the prices on tags at each store location.
Let them send out flyers saying item A is $20 *plus local taxes but when you get to the store the pricetag on the shelf should say $23.50 or whatever the markup ends up being at that location.
