klappis: I don't know about you guys but recently noticed GOG continued trend of slowly raising prices for many games the last couple of years when Steam instead haven't.

Take one example the game Stellaris. Just two months ago during sale at 75% it cost €9.99 now during the same 75% sale it suddenly cost €10.09. It's original price €39.99 still remained the same though. There even more examples where the price hikes are higher especially during sales.

Can someone please explain this?
