Do Early Acces Access games get discounted during sales?

Early Access titles aren't forbidden from having sales, but it depends on the publisher, just like any other game. Some might not want to do sales.

Well they will get at least 20% off .

Killing Floor 2 had a 15% off sale so it might get 15-20 during summer sale.

World of Diving prolly will get 50% though after last update ( from Unity 4 to Unity 5) game is unstable with often freezes for me.

Trine 3 also might get 15-20% sale.

Grim Dawn might get 50% off like past sales .

So yeah, its possible for EA games to get 50-75 % if you wait for them to hit daily featured or flash.

I hope the Darkest Dungeon gets a -25% or more. I need that game.

Early Access can go on sale and often do if its popular.

Galactic Civilazions III was in Beta during the Winter Sale: -50%.

I guess you didn't see TUG at -95% recently.

Yes, they do, in the end, it all depends on the developers/ publishers, they are the ones who decide if their games go on sale and how much the discount is.

Getting discount is common. Getting bundled.... well... even more common if not the same.

I have seen almost all early access games go on sale during summer or Christmas sales.

Some take a tiny 10% OFF, some take an 80% OFF. Keep some money at the corner and go for a big deal!

yes, why not.
