GOG Location

Hello ! I've setted up my Linux Mint so when it boots up it is connected to a VPN server in Switzerland (I don't live there). When I wanna buy a game on GOG, I turn off my vpn, then open heroic, I have the amazon and Epic Games shop of my country but GOG is stuck on switzerland prices. Do you know any solution or must I use a web browser, connect to GOG and buy my games from the web browser ?
