Each player that purchases the Mines of Moria Pre-Order gets one in-game item token. If a player purchases the Complete Edition, they get two in-game item tokens. If they purchase the Collector’s Edition or participate in the Early Upgrade, they get three in-game item tokens. It all adds together (so a player who Pre-Orders the Collector's Edition gets a total of 4 in-game item tokens).
