OK so I started with this new website called DailyScoup.com They are looking for Bloggers as their main source of traffic and they are paying out for that traffic. http://bit.ly/ulM7BY
Second to that, if you own a business and want to post your coupon for free, http://bit.ly/ulM7BY
They just ask that you offer at least 50% off.
Lastly, though it is still really new, for $1.00 you can purchase these 50% off coupons and print them out. It is like Retailmenot.com but everything is 50% off or more.
