Each full Draft Booster display your customers pick up gets them a Standard-legal promo card not found in the set's Draft Boosters (while supplies last).
For each Standard-legal set, WPN member stores automatically receive Buy-a-Box promo cards to reward their earliest box preorders and sales.
You can also sell advance booster boxes at Prerelease, in quantities equal to the number of Buy-a-Box promos you receive. These booster boxes can be purchased from your Preferred Distributor and the amount you are allocated is based on your total Tickets and Engaged Players.
Our recommendation: One promo for each Draft Booster display purchased, while supplies last.
