Staff approval note: eBook is extremely short and low on detail, also is a little hard to follow but does get to the point. This is NOT the better method that is currently out there, but this method still works. Chance of billing is possible for every product, so make sure you are very careful in how you deal with the SE. This method REQUIRES small initial investment to prevent billing/prevent stress and time loss. I would say for the actual information and effort you're getting, 250$ is overpriced. Good luck with sales!
