Soon after the first announcements (we create a Facebook page, friend invite only, not paid activity), my friend suggested to try Bee Informed in advertising his daily deals in a cake shop he owns. He wanted to try something new, while giving me some opportunities and visibility.
After some time, he get his first 20 followers and we did an experiment. We announced some cake discount which is valid only if you say that you come via app.
He get back to me next day and was quite disappointed, saying that only 1 customer showed up and called for discount because of the app.
But for me it was really a big deal. Because the whole circle of information was closed.
