You earn points for your internet searches like you would do on yahoo or google. These points can be redeemed for merchandise and gift cards on their site. It takes time to build them up but I have gotten my husband to help out by doing some internet searches in his spare time as well.
I have also found that if you follow SWAGBUCKS on Twitter and Facebook there are helpful hints and codes to earn extra points.
I mention MEGA SWAGBUCKS Friday because today is the day each week you have a chance to earn even more SWAGBUCK points. I have been very lucky with this over the past few Friday's!
Last month I earned enough points to cash them in for a $20 Target gift card!
