I'm sure this has been posted before but new stuff comes up all the time.

So:

What are your favourite free or low-cost resources for TTRPG stuff?

EG during my brief miniatures phase I bought old board games missing some parts, for the little miniature guys in there.

I also think Trello is an absurdly helpful free tool for world building and for managing a campaign as a GM.

Obsidian is a top-tier local knowledge base manager, it's how I organize all of my notes for a game.

A few stacks of index cards, a few sheets of poster board and a tub of sharpies are good for anything.
