The Trolls are having their annual 12 Days of Christmas Sale: link
Perhaps the most notable thing is that at least two of the deals (the 5th Day and the 10th day) include the yet to be released infamously delayed Castle Keepers Guide. For those who don’t know, the CKG has been in development since 2007 (at least the product page for it at Amazon has been up since then: link).
The 5th Day Deal is tempting in a novelty fashion because it includes digest-sized versions of all the rule books.
Questions and answers about the deals can be found here: link.
Given that I just ordered some stuff on Black Friday, I’m going to pass, but this sale is always a good way to get in on C&C if you’re interested.
