A limited number of copies will be available in the pledge manager after the campaign.
You will be given the opportunity to purchase additional copies of Treasure Mountain, the Caverns of Gandum and metal coins. If you wish to add the fund to your kickstarter pledge you may do so. This will help to unlock the stretch goals faster.
Yes, please select the retail pledge level and read the description in the pledge notes.
