I'm interested in subscribing to the Pathfinder Battles Subscription but am uncertain about the pricing. When I add it to my cart it lists as 279.99 per case and 10.00 for the case premium but it says that is for the first set. What does the price per set go to after the first order. Specifically if I sign up for the subscription for Deadly Foes and pay 279.99 plus the 10.00 for the Clockwork Dragon vs Spawn of Cthulhu, what will I be charged in April for Pathfinder Battles—Crown of Fangs with Pathfinder Battles—Crown of Fangs: Court of the Crimson Throne?
