Does the Pathfinder Adventure Path subscribers savings stack with the sale price of GM Day sale item's price? I went to order some Pathfinder Society scenarios and it seemed to me I was not getting it. I did not place the order in case there was a mix up.
The Pathfinder Advantage does not typically stack with other discounts (generally, the only exception to this is the holiday promo code during the winter holidays).
The system applies whichever is the greater of the two discounts.
