Walmart currently has space available on their Consumer Advisory Board for people age 18-24. If you fit this demographic then head over and apply before these spots fill up. This Advisory Board allows you to earn great prizes, such as DVDs, electronics, and more in exchange for your opinion and for completing surveys.
I haven't been able to try out this panel as I am older than 24, but so far I have only heard positive reviews. If you get in, please let us know how you like it, and we'll be sure to let everyone else know when they start recruiting for other age groups.
Go here to apply.
