The real issue with subscriptions is that you're probably paying for stuff you've forgotten about. Before you do anything fancy with bundles or rotating, sit down and actually audit what you're using. Go through your statements for the last month or two and honestly ask yourself which services you watched something on. If there's even one you didn't touch, that's your first cut - no math needed, just cancel it.
After that, bundle deals do make sense, but only if the bundle matches what you actually want to watch. Don't grab a package deal thinking you'll "get around to" the sports stuff or the back catalog - you won't, and you'll end up paying more for features you don't use. The rotating approach works better than people admit, but not because you're disciplined about switching. It works because the moment you realise you genuinely miss something, that's a signal it's worth keeping. The people who fail at rotating are the ones who sign back up without thinking and then never cancel again. Make it intentional: if you rotate off a service, set a reminder three months out to ask yourself if you actually missed it.
One thing that gets overlooked is sharing costs with people you trust. If someone in your circle has a different streaming habit than you, you might actually come out ahead splitting a couple of subscriptions rather than each paying full price. Just be clear upfront about whether people are gonna chip in or if one person's just being generous, because that's where friendships get awkward.
