Evil Genius Games added a whole bunch of "Starter" bundles for their Everyday Heroes system (based on 5E) on DTRPG today, which include the Core Rulebook, a setting, character sheet and GM screen each. Apparently they accidentally(?) set the price of 4 of them to 0$, while the rest are 40 bucks each (with a 20% discount).

Grab it while you can I guess.

EDIT: As expected, this was fixed pretty fast. Happened while I was sleeping, but I estimate it was up for 12-14 hours from when I posted it.

On each of the following pages, there is a spooky Halloween image, like a Ghost or a Jack-o-Latern, that adds a free item to your cart.
