How does it work?
It's pretty straightforward. Sign up for free and use a cash back site as a portal to online shopping. Click on a store you want to shop and it will take you to the retailer's website, and enjoy shopping as usual. You are still shopping at the retailer's store, you just go through the cash back site to get a percentage back on your purchase.

After a cash back site verifies your order, you will receive cash back. Each store offers a different cash back percentage. Percentage can change depending on the promotions they run, so you should keep an eye out for your favorite store's deal.
