Isn't it funny how the cheapest option always seems to cost you something else, just not in money? Same thing happens with budget flights, early bird deals, even cheap apartments. You save cash but pay with waiting, bad timing, or a rough location. In my experience the real trick is just deciding what your time is worth before you book, because $19 plus two hours at a gas station might really be $19 plus your whole morning. I've started asking myself that question up front now and it saves me a lot of regret later. Though sometimes the cheap version is still worth it, so your mileage may vary depending on how much you value that extra sleep.

The number thing works because it gives your brain a finish line. When you just say clean until it feels right you never actually stop, you just get tired and quit halfway. I do 10-10-10 in the kitchen every few months and it takes maybe half an hour. The count keeps you moving instead of sitting there holding a shirt for five minutes asking if you love it. Spark joy is fine for people with tons of free time but most of us just need a dumb rule that gets it done.
