Sign up for class action settlements. Every few months I go to topclassactions.com and go to the open settlements section. I sign up for every one listed that doesn't require proof of purchase. I also double dip by signing up in my partners name.
It's not a ton of money but I probably spend an hour doing it whenever I think of it and occasionally get some surprise money a year or so later. Usually they end up being only a few bucks, but over the years I've gotten thousands from it. Just got 2 $89 checks last week.
