Then keep an eye on the trademark deposited in the usa & cross the fingers

About prices, it's an interesting subject since here we pay around 80 to 100€ one boardgame (descent, myth, zombicide, space hulk v3, super dungeon explore, mansions of madness etc)
There are some around 60€ (doom, dungeon quest)
it's around 45 to 50€ one expansion of a boardgame including postage & package.
Another interesting fact : you want to buy a game in british english from the usa, for instance let's say D&D Castle Ravenloft.
The price will be around 60€ including postage & package from a french retailer.
Buying idrectly from the usa costs less but if the douan catches your package, you pay the VAT (20%) on the total amount + 26€ more for the file fees ...
Dwarven Forge made an interesting offer in the usa with the new tile system kickstarter but it wasn't the case at all for the rest of the world due to vat and high postage fees.
So HeroQuest only time will answer to your question.
