I've been joined up with NCP (National Consumer Panel) for quite some time and have been enjoying seeing my points rack up.
NCP is a panel that wants your opinion! If you sign up with NCP they will send you a scanner so you can scan things you buy and upload it every week which in turn gives you points that you can exchange for products! They have some amazing items, which includes high end things like a flat screen tv and an ipod touch! It's easy to earn points, and you also will get surveys to fill out that also give you points.
NCP is also doing a sweepstakes on their facebook page, for a Kindle Fire!! You can check that out HERE
