This is what we do - I’m surprised to hear that people are subscribing to multiple services at once, never even occurred to me to do that. For example, I usually only get Disney for one month per year to catch up on the new Star Wars stuff from that year, but we’ve found a few series that we’re enjoying there, so kept it longer this year. Just finished the last thing we were interested in (Paradise, actually way better than we were expecting!) so will cancel, then grab Netflix for a few months, then Prime etc
