purchasing paizo / pathfinder from roll20 / demiplane stuff question

I see in the marketplace there's several new items for pathfinder 2e remastered mini campaigns, but they all say something like, the adventure text is in demiplane.  the stuff in marketplace for example shows $12.99 and appears to be just the maps.  Demiplane has stuff for $24.99... do we need to buy both things or just the demiplane stuff or...  i'm old and dum lol.  do we need to buy both things from demiplane and roll20 for $36-ish ?  thanks!

Hey there. If you purchase the $24.99 on Demiplane it should (is supposed to) come with enabling the Roll20 product that you're looking at. In other words go pay Demiplane the $24.99 and you don't need to additionally pay Roll20 the $12.99 --- I'm pretty sure. It says this in the description where it says: You can receive this Roll20 VTT Companion for free by purchasing the  full-featured digital book on Demiplane. Hope this helps! The $12.99 version on Roll20 is for someone who already has the adventure text in a book in any other format (such as a book, or a PDF, or effectively free included if you have the Demiplane version). 

Awesome thanks fam!  <3
