If you're looking for an easy way to make a little bit of money, you'll find some great free money options on this page.
This page is an index of offers that allow you to get money without any work. This includes things like searching for missing money that is owed to you (definitely worth a few minutes of your time), credit card and bank account signup bonuses, apps with signup bonuses, apps and websites that pay you for access to data or other participation that doesn't require work from you.
Possibly my favorite option is SaverLife, a non-profit organization. You can earn money each month (up to $60 in total) for putting your own money into a savings account. The program encourages saving, and will even pay you to do it!
