About the pricing:
Even though the prices can look high at first sight, if you will do the math, you will realize they aren't so big.
Let's take the 50 blogs pack for example, that costs 3800$ / year. That would mean 316$ / month. And yes, 300$ per month means 2 crap services you are already buying for link building, and let's admit...the results will never be the same. The serp boost a privately owned network can generate are way better than all the current SEO's are providing on forums right now. Most of the medium-big companies are using such networks with good success for years. So, if you decide to own such a network you will not waste money on cheap services that never help you rank.
