Similar to Swagbucks and Opinion Outpost, Superpoints is a reward site. You can use the Superpoints Network with confidence. "They accredited by the Better Business Bureau and Truste, and many of our advertisers are brands you know and trust like The Gap, Target, and Macy's."
I won 100 superpoints using the Superbutton. This is a button that allows for 30 spins a day to earn points. A lucky few win 100 points, and when you do if you get a friend to join using the given code they get 100 points too.
This is an invite only site so an invitation is required to join.
