Other countries aren't messing with the price tags though. they simply show the final, total price to be paid. Like if you have that amount of cash and nothing more, you will get the ware you are buying.
So in any practical case Apple is being dishonest (due to law) with pricing. Also let's not forget that when Euro was like 20% higher than Dollar, Apple pretended that 1 USD = 1 EUR. There are no possible "tax" or "laws" to weasel out of that, it was pure and simple price hike for no reason at all. (the VAT for EU was added on top of the already increased price due to incorrect conversion rate, so that wasn't it)
