"There is just over a week left to take advantage of the rain17 discount code! Remember, this discount will stack with the Pathfinder Advantage discount that you receive from subscribing to the Pathfinder Adventure Path. *It does not apply to subscriptions, backorders, preorders, or downloads from companies other than Paizo—but remember, you can only use this code once through March 5, 2017.
If you're looking for a good place to use the rain17 discount code, we've added many products to our Golem Sale & Clearance section! The code will also stack on most products here as well. We will be routinely adding more products to this section, so check back often!"
