So of the anniversary rewards are gifts that will be awarded to anyone with a fully purchased pledge package by the end of the month, others are simply unlocking the item in the store. So you do have to read each reward. The otterbear pet and the otterbear mount if we get there are both store unlocks so you will not receive one as a gift but they are available to purchase in the store when they would not have been otherwise (well unless attached to a barge!) Those that are gifts will be added to your inventory after the month end but we do not have an exact date.
