Storyblaster only charges a 15% service fee on top of your promotion spend. Most agencies not only get hefty upfront fees, but also charge 10%-35% of your entire campaign raise to simply do promotions and ads. The amount you enter in the promotion window in the ENTER YOUR BUDGET field is the full amount spent at Facebook, then the 15% fee will be tacked on. (i.e you enter $50. That full amount goes to your promotion, and an additional $7.50 will be added to your payment).
Reaching both inside and outside your network is critical for campaign success and no other tool provides this reach for such a low cost. We recommend spending a minimum of $50 per promotion. The more you spend, the more your return will be, which can mean the difference between campaign success and failure.
