here’s something for the tech wizards:
I added the Pathfinder-Campaign-Setting-Inner-Sea-Poster-Map-Folio to my cart and now every item in it has the note „You purchased this product May 11, 2019.“ which I’m sure I didn’t (only the map folio)
I've created a ticket for this so we can address it once we get back from GenCon. It looks like if a single product triggers the code for the previous purchase note, it displays for all products on the order, just as you noted.
Thanks for letting me know about this Dropbearhunter. :)
