Anyone know of a way for a college student who has a job to make some more money?

Currently I have a part time job and in a couple weeks, I will be starting my junior year of college. It is my first year after transferring from a community college at a university. I was just wondering if there are some other creative ways to make money or receive ‘points’ for stores like amazon, etc? I already do some surveys for SurveyU; maybe there are some other sites that give points for surveys?
Thanks for your help!
