Ever heard of Swagbucks? I've been doing it for a few months and have already earned $30 in Amazon Gift Cards. Amazon has some pretty sweet deals on diapers so I've been scoring free diapers using by Swagbucks :) Right now I'm averaging a $5 gift card a week just for using the Swagbucks search engine instead of Google. You can also redeem them for lots of other gift cards (Starbucks, Lowe's, I-Tunes, etc.) or prizes.
It's really easy - you sign up for an account (just click below on the icon which will give me credit for your referral) and use the Swagbucks search engine to search the internet. You are randomly awarded "Swagbucks" for searching and every time you earn Swagbucks I will too. You can also earn swagbucks for taking surveys, taking polls, making purchases online through websites such as Walmart, Target, I-Tunes, etc.
Hope you'll sign up! Let me know if you have any questions. And... they won't harass you with junk e-mail in case you are worried.
