Hello, I just wanted to ask if this and the Ravenloft and Krynn collections are/were on sale sometimes?

I have never seen them before and I did not even know that GoG sells them.

Thank you in advance!

i got both collections a while back during one of the mega-sales
i figure that they will go on sale again in one of them eventually
best way to keep track of when they go on sale is to wishlist them
and make sure you get email notifications in settings
