Two questions about D&D 5e compendium materials

Hi Danger Zone (that's fun to say :D ) We don't generally offer or allow discounts on Roll20. We feel the culture of discounts in this space devalues great art, and one publisher doing it pressures other artists to devalue their work in order to compete. We don't release bundles of content that have been previously released on the platform, as that would constitute such an example. This also helps you, the customer, know that if you brought it at one price, there will never be a situation of wishing you held off. As for Xanathar's - we hear you (and many others) loud and clear. We held off on publishing the PHB for quite a bit until we had features in place to make the integration amazing (hi Charactermancer!). We're approaching Xanathar's the same way, but I expect there to be news soon(tm).
