Since this morning all prices on GoG are in ' $ ' instead of my usual ' £ '. There is no way to change this in time and currency, it's locked onto the $.
So America has finally invaded us?

Have you tried the following?

Account tab on the upper side -> Account management -> Account and locale tab -> Currency?

I did not get or see any changes on my side.

Edit: Apparently you did and I did not read it, apologies for the redundancy. I can't think right now of anything else that might explain that.

Have you tried clearing cookies and logging in again?

I used a old browser profile that hadn't been on the site in ages and the site was in polish and the currency was in dollars I had to clear cookies to get it to work properly.

I will give this a try, ty.

Okay, cleared cookies and now it's change to bloody euros. What is going on with GoG lately? They are coming undone.

If you know how to check the contents of your cookies the one that you want to check is gog_lc.

Sometimes Cookies have an expire date and get all dry.. Trust me I had to deal with 3 month old DARE cookies, not fun if you ask me. but yeah refreshing your stock is always good to make the site like you more.

maybe gog is already preparing for brexit :P.
Payments in € only then -.- .
But ya honestly speaking if deleting the cookies didn't work maybe try another browser - just to confirm if it behaves the same.
Also resetting your internet connection (restarting router) might help if gog is using some weird geo ip mapping to change the locale and maybe thinks your ip address range is from continental europe

I have problems too but in my case it is that the website tries very hard to change to the local currency all the time instead of the one my wallet funds are in. Makes it hard to buy any games...

And you thought there'd be no consequences to Brexit.

Waaa! It's just reverted back to dollars. I give up.

Has to have something to do with this **** new web-site of theirs.

Sweet, €uros aren't available anymore in Account and locale tab -> Currency. Only $ !

Trump conquered the World !!!

Earlier today the website spontaneously changed itself to Polish at my end. GOG's site is constantly on the verge of breaking down, you get used to it.

I get placed all over the world. It was Russia for over a week and today it was Poland. This has gone on for several months. I am nowhere near these places even if not thousands of miles removed.

That's nice - I usually get German or Russian :).
