Freyr-O: While I can still select one of the three currencies (local/dollar/euro) in the galaxy client, when I buy through the browser, I've had only prices in the dollar (no local or euro) for the last couple of days. What causes that? Is this some sort of bug? Do you also have it?
I attach a picture to illustrate the problem.
I would recommend clearing cache and cookie files :) Also double-checking if your preferred browser is updated to the newest version (you could also try incognito mode).
Some users have already mentioned that putting a game in your cart and proceeding to checkout can help as well.
Still, if you still have any problems after trying the above, please contact
GOG Support :)
