DriveThruRPG has two bundles out for Pride Month! They include various TTRPG's (supplements and core rules) as well as comics, novellas, and more. Each bundle allows you to get over $350 worth of various RPG content for only $25. Meanwhile, all proceeds will go to support one of two following charities:
Outright International (Outright) is an LGBTIQ human rights non-governmental organization (NGO) that addresses human rights violations and abuses against lesbian, gay, bisexual, transgender and intersex people.
Tabletop Gaymers Inc. is a nonprofit organization whose mission is promoting diversity, equity, and inclusion by championing the visibility and recognition of the LGBTQIA+ (lesbian, gay, bisexual, transgender, queer/questioning, intersex, asexual, and others) community through tabletop gaming!
Each bundle includes different titles. For example, Bundle #1 includes Girl By Moonlight but not Thirsty Sword Lesbians, while Bundle #2 includes Thirsty Sword Lesbians but not Girl By Moonlight.
Both of these bundles are only available for a limited time, but I'm not sure when they expire. You'll probably want to grab them ASAP if you're interested in getting the savings.
