When you shop online, don't limit your money-saving efforts to coupon codes, deal alerts and price comparisons. You can also benefit from cash-back sites that let you earn back a percentage of the money you spend on qualifying purchases.
Here's how it works: You register with a cash-back site typically by providing an email address and creating a password. Any time you want to shop, sign in and then click on a store from the site’s list of retail partners. If you buy something, the cash-back site gets paid a commission by the retailer. The site then shares a percentage of that commission, in the form of cash back, with you.
