Every PDF for a PF1E Player Companion or Campaign Setting book I've added to my cart today has shown no discount. I was expecting the announced 30%, which is being applied for other PF1E and PF2E PDFs.
Maybe this is a bug, possibly caused by the fact that these two PF1E categories do not have a separate "Digital Editions" section. With physical and digital all in one category the PDFs may not have been flagged for the discount.
It is also possible that no discount for these categories is entirely intentional, in which case I will simply be disappointed and move on.
