If you are a user of SwagBucks and/or MyPoints, then I have a quick earning opportunity for you. All you have to do is write a review for one or both of the sites, and you get paid $10 per review!
Additionally, you get free upgrade coupons. You can upgrade your accounts on these sites to earn more in the long run. So, if you are interested in this, please let me know through a PM here on MOC.
P.S. You can only do this if you have been a user for quite sometime (a month or more).
