Right now Ebates is running a promotion where if you refer at least 4 friends you can earn $40 or more (on top of the normal $5 per qualifying referral)! Sign up for Ebates and check out all the details!
Now if you don't know about Ebates it's pretty awesome! I actually just used Ebates on Wednesday to get 1% cash back on plane tickets I was buying anyways. Whenever I shop for ANYTHING online I always check Ebates first and most of the time I can earn cash back for a purchase I would have been making anyways.
So if you haven't already, hurry over to Ebates and sign up (it's FREE). Start getting cash back and getting paid to refer your friends to get cash back!
