OPINION OUTPOST
Looking to make some free money? Have a few minutes? One of the best survey sites I've found and stuck with is Opinion Outpost. They offer you quite a few surveys per day. (I think I get about 3 or 4 a day) You get points for completeing the surveys and can turn those in for cash or Amazon gift cards.
Think Christmas! Last year I used mine to get magazine subscriptions from amazon. The gift that keeps on giving!
Side note: All You magazine usually had about a hundred dollars worth of really good coupons each month.
