kaerius: Looks like they changed the base price instead. Indeed for me it's now a 41% discount from the previously listed standard price(and 22% off the previous 25% discount price).
I bought it for ~€21(200 sek). Over on steam it's €28(266 sek), so about 25% off the steam price.
gbblackknight: It's the same price on Steam, for me ($32.99). I too got this "25% off" email, only to see it's the same price...
Odd things going on with the price points for sure. If that's US$, then your price is 40% higher than what I paid on GOG, 5% higher than what it's listed as on steam for me...
Sidenote: just occured to me that I might be getting better prices on gog because it's a european company, and I thus pay their (polish) VAT, not my Swedish VAT(which is 25%) like on steam. *Checked* 0% VAT within the EU from Poland, interesting.
