Found an aggregate site with a comprehensive list by state. The ones I tapped into are metro and have no online order options which makes them inaccessible to many.

To be fair, oil paint keeps for a really long time, I’ve used decades old inherited items, so I can’t imagine a lot of it gets donated. And I wouldn’t trust used acrylics for the opposite reason, as it tends to solidify in the tube over time.

It’s a neat idea, but access online is something most people rely on, so, after Blick, what is there, online?
