There must be a lot of examples of people who don't pay attention, because I've seen a few advertisements on TV for an app that basically finds and tracks the reoccurring charges to your credit cards and allows you to instantly cancel the ones you don't actually use or need (which, I'm assuming, means you need to give this app access to your credit card information and charges which I wouldn't do). Personally, I only have 2 things on auto pay, everything else I pay as I go, and like you, I check every bank and credit card statement monthly.I'm amazed at how many people I know who don't seem to even know what they're paying for. It's just so foreign to me because I look at every credit card charge. One of my friends told me something like 10 months went by before he realized he'd been paying for some kind of sports package on YouTube that he wasn't using. I think he said it was around $100 a month. I even questioned that amount, but that's what he said.
I'm sure companies love that some people don't pay attention to their finances.
