On that note, the only relatively convenient exception I know of is Bandcamp Fridays. They're specific days where Bandcamp doesn't take any share of purchases.

I wish this were a more common practice, and I wish I could allocate my Netflix/HBO/prime/etc. subscription dollars to support specific titles. Instead, shows get cancelled because people didn't stream it enough on day 1. I want a s2 of Tales From the Loop, but it's still in limbo with no way for fans to show support.
