Check your public library. If you are lucky enough to live near a big one, they may have all the shows you want to watch on DVD already.

I live in a large metropolitan area and belong to 4 different public library systems. Two of them have branches within walking distance of my house. For either of them, I can go to their website, search for a dvd, and have it delivered (for free) to the branch closest to my house.

It's not instant gratification -- it takes a couple of days. But in some ways, that's a feature, not a bug.

On top of that, they also have Kanopy (a streaming service offered via libraries). The selection is NO WHERE NEAR as complete as major streaming services... but, it's certainly nice to have.
