YouData is another way to easily earn small amounts of cash on the internet. You will not get rich, but what's pretty cool is that they deposit the money that you earn each week to your paypal account. All together, I've probably earned around $15, which covers the few postage labels that I randomly print from paypal when I sell something.
Basically, you are shown a few ads and you just have to click on them. You will only get around 5-10 ads a week and all you have to do is click - no surveys or anything to fill out.
Just thought I'd share! Every little bit helps. :)
