Stonelesscutter: I'm having the same problem but slightly different.
The website (now) shows me prices in GBP, which is correct as I'm in the UK.
In the past, Galazy showed me prices in EURO which is fine for me too, as when I started my GOG account originally I lived in a country which uses the EURO.
Now however, Galaxy keeps showing me prices in Polish Zloty, no matter what I do.
Changing the currency in Account Management has no effect.
Would appreciate any assistance. Thanks in advance.
