Deleting cookies an cache unfortunately does nothing. I got the same Problem right now. As soon as I go to checkout, my currency gets change to USD with absolutely no option to change it back. I can edit the cookie back to EUR and the store has EUR again. As soon as I go to checkout it changes to USD.

- Logged out of GOG
- Deleted Cookies and Cache
- Closed and reopened Browser
- Deleted Cookies and Cache again
- Closed and reopened Browser

Did this multiple times but every time I want to pay my games it changes back to USD. This has to be a bug on GOGs end. Some kind of script does something weird.

Hello, a month later.

If you have contacted GOG support, you may have received a message by now. So be sure to check, eh.

Something i'm not seeing mentioned in the topic is the use of VPN. If you are using one such a service, either individually or incorporated into your browser that sets your location to anything other than Europe or uses a hub outside its area, that might trigger an error on GOG's side of things.

Another issue might be the ISP taking an unusual route to reach GOG's servers which again might trigger an error on it's side of things.

Or it might be not related to GOG directly and instead has something to do with a payment processor. Using PayPal for example has proven problematic for some users in the past.
