I recently placed an order for a couple of Dungeon crawl classic adventures and the new critical hit deck. One of the adventures (Saga of the Dragon Cult) is on Pre-order. I chose to wait on my order and combine shipping and wait for the whole order once the Pre-order is in stock. Would it be possible for me to change my decision and have my crit deck and second adventure ship out and leave the Pre-order item in limbo until it is in stock?
