Those with Amazon Prime can claim free games. Either for GOG or Epic platforms.

So the next " major " sale will be at the end of this month ?

Next big sale should be the Black Friday, and several weeks later, the Winter Sale.

Well, the Black Friday sale is usually one of the largest sales of the year and if I was a gambling man then I would guess that it would start on either the 25th or 26th of November. We will have to see if there can be an anniversary sale squeezed in between the end of the Halloween sale and the start of Black Friday. It should not be impossible I think, there are a couple of weeks left until Black Friday starts

Big Sale:
