Another post related to the sketch cover subscription caught my eye and it made me realize that I didn't receive the Pathfinder Beginner Box: Secrets of the Unlit Star either as a Pathfinder Special Edition Rulebook subscriber.
I went to double check and it's still listed on the subscription page as being a part of that subscription:
Pathfinder Special Edition Rulebook Subscription
If it is not supposed to be included in the Special Edition subscription, it really feels like a frustrating extra step needed for subscribers to have to monitor any news for these one-off products and then sign up for the regular subscription for one month and then cancel whenever they come up.
Edit: Edited to make the link an actual formatted link.
