Prepare yourself to get lost in the largest collection of free stuff on the internet
The title of this post is not hyperbole. At least not that we know of. We lost a bit of time just scratching the surface of links in this simple and great post by JHarris. So pull up a chair (or sit up in bed, this is a judgement free zone) and check out a few. Be sure and read the thread too, because Rhaomi has a comment that was Flagged As Fantastic by a few people and yeah, that's putting it mildly.
It's a link laden comment about sideloading on the iOS to have more alternatives to the common, and increasingly expensive, streaming sites. Thank god it's the weekend, so there's plenty of time to check out all the suggestions!
