Earn Cash for Surveys at i.think inc.

They'll give you cash, prizes, or contest entries for doing surveys. I've been paid by them before and am awaiting another check to be sent on 12/3; they're a reputable company. If you'd like to try 'em out, here's my link to join (thanks!): http://www.ithinkinc.com/Referral/?MTNfNjY3Mzk3XzIy

Note: They're only accepting US members right now.
