If you are really serious about making money, though I cannot say whether the Zaken Corp is a scam or not, I will say that there is at least one program I have tried and made decent money with, and that is Mystery Shopping. With Zaken, you have no way of knowing how much your effort will get; with mystery shopping, you go out to a shop knowing exactly how much you will need to spend and how much you will earn. It helped me pay off my credit card after my daughter was born, and I highly recommend it. The Mystery Shopping Directory here is the very one I bought into and used, and it more than paid for itself in a couple of weeks.
For other ways to earn money, just look at the sidebar to the left. I try to keep this as up-to-date as possible. Also you can see what I'm doing on Twitter over there too! Feel free to contact me through my profile if you have any questions.
