I am also a member of DealBarbiePays.com, a great site where you can get paid to try out new offers and products. It is similar to Cash Duck and you can click below to get in on the action
I have not gotten paid from this one yet but I am working it. You can sign up as my referral and then your own referrals and start to make a percentage of what they earn.
You can also click here to sign up. I am not sure how many of the stories are true because I have not gotten paid from Deal Barbie as yet but I have seen people report as much as $1000 made from the various offers on the site so you may just want to sign up now and start earning cash and referrals.
