Itch doesn't have the option to make a bulk sale unfortunately.
The price is intended to be low enough for players to pay for their own license, so that dms won't have to cover the whole cost. The players will also have their own license so they aren't that dependant on the dm or can run a session on their own if they want to. I'm sure if they like the idea of this project they will consider providing the means to support it this way.

Yeah, I understand. It's not that much. It's just that two of them are fresh in college on their own. But I'll be able to cover the expense for all of them, and they all can pay me back when they are able. Real quick, (I haven't opened up the software yet) is there anything else you do other than have character sheets open in a browser window? Any other tips for making the use of the app easier with other platforms like DNDBeyond?
I highly recommend checking out the tutorial videos to get started. Other than that I have no recommendations. In the current version, dice rolling is on the players side only. So the dice are not networked yet. That might be an issue if you don't trust your player with the rolls ;) I will add it with one of the next patches though.
edit: Just put out an update that introduces a chat box and prints out dice results in the chat.
