Sometimes we need to try new things and go beyond what has worked for us in the past. Of course we are recommending calculated risks rather than blind leaps of faith. For instance, if Facebook and Google ads are no longer giving you the desired results or those approaches have never produced desired results...perhaps it would be a great idea to try Groupon, Living Social or Four Square.
First do your homework: ask around to see who has had any experience with any of these services. Do not stop there, go online and gather as much useful information as you can. See if a site like Lifehacker has a how-to guide. Once you know how everything works and what are the potential risks then start as small as you can. As your confidence grows and if you see desirable results take things to the next level or try a new strategy.
