I really need to tell you about MyPoints.com. I signed up for this in college, and the rewards have been plentiful. Once you sign up you'll start receiving daily emails--warning, sometimes you'll receive SEVERAL in one day. They're ads based on your interests. At the end of the ad there is a link--click it--receive 5-10 points (varies from ad to ad). You get 5-10 points for reading the ad. However, if you take advantage of the ad you'll get LOTS more points (hundred or even thousands).
I have taken advantage of a handful in the past 10 years, but the majority of my accumulated points have come from just reading ads and completing surveys. You also receive points from referring friends too, so if you're interested--please email me!
Okay, so once you have the points, you can redeem them for a plethora of goodies on their site--mostly gift cards to about any store you can think of. We've used our points (my husband is signed up too) to help purchase Christmas gifts, pay for groceries or eating out, and for home improvement. It really doesn't take long to accumulate enough points to start redeeming, and seriously, it doesn't take long to scroll through an ad.
Every so often I get an offer via MyPoints for something really cool, like today: http://www.shop4freebies.com/
Oh. My. Word. Who doesn't like free stuff? We have a motto in this family: cheap is good, FREE IS BETTER. This site links you to hundreds of other sites to get FREE STUFF--free food samples, cleaning supplies, health items, and more. I just completed a few forms for a handful of items, PLUS I got 5 points for MyPoints.
