I subscribed to the Disney+ streaming service.
The immediate reason: Some time back, Tamara and I were called away on an emergency right in the middle of Avengers: Infinity War. I had already seen the movie. She hadn't. I've also seen Endgame, but she hadn't, and she also thought she had missed the Winter Soldier and Civil War installments of the Captain America storyline (when I started those two, she immediately realized she'd seen both of them after all).
All that stuff moved behind the Disney+ paywall a little while back, and renting those four movies, or even two of them, would have cost as much as or more than a month of the full service.
So, the weekend before Christmas, I was over at my mechanic's house doing unskilled things in facilitation of his repairs to our family car, and he was re-watching the season finale of The Mandalorian. I tried to make myself not notice, because I didn't want to get hooked on a show I'd have to pay extra to watch.
I don't know if I'll bother watching that show, but it got me thinking: A Disney+ subscription would let me re-watch all the Star Wars movies, and all the X-Men movies, and all the Avengers movies. And I could watch all that stuff in a couple of months, which would be $13.98 in subscription fees.
So that's what I'm doing. We watched the end of Infinity War. Then we watched Endgame. Now we've watched the first three (in story order) Star Wars flicks and will likely watch the other six in the next couple of weeks. And so on, and so forth.
Heck, I even watched the latest version of Mulan just because I could and because they were charging non-Disney+-subscribers something like $20 for it last time I noticed. Not my kind of thing, really, but not terrible.
