Instead of going directly to where you want to shop, you first go to the cash back site and search for your desired retailer.
The cash back site will link you to your retailer, and also provide you with coupon codes to save you even more money when you shop.
Once you make a purchase, a percentage of that purchase price will go into your account.
Each site works a bit differently, but several times a year, you can redeem the amount in your account to get a check, a gift card or a PayPal deposit.
Using these sites is a great way to get a present for Mom, and a little something for yourself, too.
