On facebook I have the fluff friend application and one way to earn the fluff "munny" is to take surveys. Then you can use the munny to purchace stuff for your little fluff pet. My fluff friend is a cat named Snowdrop. Anyway so I took a survey and got 200 munny and as an unexpected bonus also managed to get a $5 Amazon gift code. Wee! Not that $5 goes far, but it's still something I didn't have before.
