TzarHar: A VPN to circumvent the region lock would be another solution.
Timboli: Many folk seem to believe this, but in my experience it isn't true.
It would only be true if a country check on your payment method isn't in place.
Not to mention, that when you log into your GOG account, GOG know immediately what country you are from ... unless you used a VPN when signing up.
Be nice to get around this prevention, especially with a store like US Amazon, as they have many ebooks I'd like to get, and I have researched this issue quite deeply.
By all means though, I am very open to a non illegal solution.
Well, it worked for me, and every single time I needed to resort to it, at that.
1. Clear your cookies, and reconnect your router to be assigned a fresh IP address
2. Fire up your VPN of choice (there are open source ones free of charge) and connect to a VPN server that's somewhere else than in your actual location and for which the region lock doesn't apply
3. Log in on GOG and purchase the game in question, preferably with wallet funds
4. Log out again and disconnect from the VPN server, close the VPN software
5. Clear your cookies, and reconnect your router to be assigned a fresh IP address again
6. Optional but highly recommended: Change all the passwords you used while you had been connected to the VPN server
