Update: Now you get even more bonus points when you join!
Yroo is another site that offers points to be redeemed for cash$$. All you have to do is share the deals on FB or Twitter to earn points.
Join Yroo and invite at least one friend for your bonus points (I started with 4,500!). You will get 2,000 just for joining.
Then you can set it up to auto-share or share more deals for additional points. Click here for an example of a deal you can share.
After you join you can also enter in their weekly contests for free!
