News from the dev update:
With the physical box set of the Essentials Kit, you can unlock the the Dragon of Icespire Peak adventure on DDB for free - and there will be a 50% off code for the PHB on D&D Beyond in the box, which you can use yourself or gift to someone else! There will also be a series of QR codes in the box pointing to WotC-written digital adventures on D&D Beyond that will supplement the adventure.
