I have never heard of this so I figure that some of you guys haven't either. It is legit and you can actually get money back for buying things online. I know, it sounded like a scam to me too.
Basically you go to Ebate's website and click on the store that you will be buying from online. By clicking on their link they are able to track that you made a purchase and confirm with the company. They get a percentage of that money from the store since the customer (you) clicked on their link to that specific store. The best part is that they share some of the percentage with you. Check out what percentage you could earn back by clicking on the store's page on ebates.
Some stores that are included:
Sephora 8% cash back
Ulta 4% cash back
Dermstore 7.5% cash back (a coupon for dermstore came in MyGlam's March box!)
Old Navy 2% cash back
I'm not sure about you guys but I've made quite a few orders online and would have loved to hear about this site way before now. Hope it helps you guys too.
