I have been using a company called Ebates, and Shop at Home. I started at Christmas time when all I did was shop online and so far I have earned close to $40, just for shopping through their site!!
Let me break it down for you.
-When ever you want to make an online purchase, check their site and see if the have any online coupon codes AND how much "cashback" they are offering for the store you want to shop from. (Think of it like your credit card cashback programs.) Many times they offer anywhere from 3-8% cashback.
-Your "cashback" accumulates, and either, every 3 mo or when it reaches $20, you receive a nice big fat check in the mail! Don't worry if it takes you a while to reach your $20, they never expire!
That's it, it's that simple! You are only using them as a "portal", once you find your store, they redirect you to that stores website, you shop on your selected stores webpage, but they place a tracking number on your order, and that's how they know how much to pay you!!
I wish I had known about them years ago! As a stay at home mom, and a 1 car family, I shop online for almost everything!
