For example if you are going to Kohls.com to buy something. Go to ebates.com, click on their Kohls.com link (shop the site like normal and make your purchase) and then 3-6% of whatever you purchased will be put in your ebates account. That account will slowly accrue and a check will be mailed to you every 3 months.
Registering is super easy (type in your email address and a password and you're ready to go) and if you do it by clicking on this link, I will get $10 for referring you. Yay! everyone wins.
