Price of personal license is +25% for EU countries as opposed to US. I thought it's only game distributors who do this kind of thing.
Regardless, they have promotions running for long periods, so it's easy to start with a trial and then pick up a real license when the price is lower -- the last one ended on 16 April and was 30% off, I got mine last September and it was 50% off.
In general, for software like for everything else, prices reflect what the market will bear. We are willing to pay more, clearly. It's slightly embittering that in this case they cannot bring the usual "import taxes" justification, since they're based in Czech Republic.
