My argument is based on the fact that I have seen such tags with the same price for Germany and Portugal.
It true that they don't do it for most of their products, but that doesn't change the fact I have seen such price tags.

The initial argument would only be valid if prices in different currencies would be smaller in the poorer countries, which doesn't happen anyway, regardless of currency.
But it does happen, on average H&M products are cheaper in Portugal than on Germany, except for those few cases I happened to stumble on.
