I hadn't thought about that but I don't think this particular scenario qualifies as price discrimination. It's an objective factor and it's about distance selling between countries, which is treated differently.
That being said, there should be a way for a shop to show the price dependent on delivery to a certain country, for example because the visitor, without being logged in, can select "Greece".
Alternatively, it would be great to have the net price change but the gross price stay the same).
@e-comAre you aware of any ways to achieve one of the above?
