Am I crazy to be wanting to sell a $7 per month membership using FB ads?
I understand its just a numbers game - Franks numbers of $611 (over eight days) to get 13 people (via ads AND the Halo effect), a new customer acquisition would cost $47. And it would take almost 7 months for me to be profitable (although the Halo effect would hopefully mean even more people would sign up, bringing down the cost of acquisition ;-)) ...
