What is the cheapest way to stream everything?

The cheapest approach is to rotate subscriptions rather than hold multiple services simultaneously. Watch through one service, cancel it, and move to another. Take advantage of free trials (most services offer 7–30 days free for new subscribers). The Disney Bundle with Hulu (with ads) and Disney+ provides the best per-service value. Peacock has a genuinely useful free tier. An antenna covers local broadcast TV at no monthly cost.
