8. Sign up for Ebates

It may sound too good to be true, but cash-back shopping sites like Ebates really do pay you to shop online. All you have to do is create an account, and then click through to the stores where you’d normally shop from the site. Once you make a purchase, you’ll earn a certain percent back in your eBates account. Most of the time, the cash back percentage is just 2% or 3%, but sometimes you can earn as much as 10% or 15% back. Combine those rewards with saving from a a cash-back or miles-earning credit card and you can save even more.
