The link in the blog announcement no longer works.
This is the address
https://paizo.com/products/btq023dx/discuss?Pathfinder-Beginner-Box
But it takes me to the Paizo login page.
And it's no longer showing to pre-order on the Rulebooks pages, nor in my Sidecart.
Edit:
I thought my sidecart had some other items as well, but it seems to be empty. Maps, if I recall correctly
That link seems to be working now.
But I am seeing the sidecart issue too. Mine says that it contains 19 products, but only four of them are listed.
