Tim414: Can someone tell me how to get back to the sale page after viewing a game without going through the main page each time and having to select the sale page again? It is really annoying.
It's the same for all of us.
The Nordic Sale page is actually here:
http://www.gog.com/promo/nordic_games_weekend_promo_140613 If you visit a game on the above list, and then click back, you will return to that same sale list.
What I'm guessing you are doing is instead clicking the "on sale" tab on the main page. This doesn't take you to a new page, really, it just inserts some new information into the existing main page. When you visit a game card and click the back button, you return to the main page, but GOG doesn't remember the state that page was in. You'll find this is true for most gog pages featuring lists of games. GOG will never remember your last sort criteria, they just serve the page in its default state.
