I absolutely love what these guys are doing, They solicit local businesses in your area and get them to give coupons on everything from the dentist to the beauty salon to the local pizza place. This is going to be huge (bigger than coupons.com I think) and I highly suggest that you bookmark this link and check it often. You can also sign up your email for your instant updates when new coupons pop up. If you're not rolling with these guys you are missing out.
Note: they don't have some stupid printer that you need to install and all of their coupons print as PDFs
