The estimated delivery date listed on your Reward Tier indicates expected fulfillment for the Pirates of Pugmire. For the PDF, it is expected to be delivered to all backers by September 2020. For the hardcover edition, it is expected to be delivered to all backers who have correctly confirmed their shipping address by February 2021. If the projects are completed before these dates, they will be sent to backers as soon as they are ready.
Additional rewards, particularly those generated as Stretch Goals, will be delivered as they become available. As the Pirates of Pugmire book is the main focus of the program, many Stretch Goal rewards may not be developed or worked on until after this book is completed.
