First up is Swagbucks. You do searches, find codes, and earn points. Then you can redeem those points for prizes. So simple. They are legit. They do not spam your inbox or cause viruses on your computer.
Next is Hitpredictor. You rate music, earn points, and then redeem for prizes. Again, these guys do not spam, cause viruses or scam you.
Irazoo. Works the same as Swagbucks.
There is also Mypoints, Zoompanel (which is a legit survey site), Crowdtap (discussion community with incentives (Amazon cards, etc.), and a few others.
I don't have many pictures of the stuff I have gotten on here, because I just switched over to Blogger, but if you go here : My other blog you can see tons of other stuff.
Hope this was helpful.
