Just in case others missed it, the lion's share of the revenue was not recurring — it was lifetime purchases ($3,420 @ $180 each). The recurring revenue for the first month was about $2k.

I'm also not clear on the "in one month" aspect of this, since the author stresses that most purchasers were people that were on her 4,000-person newsletter list. Presumably that was built up over a much longer time period?

Still, congrats to @mlent for launching this, adding value for so many people, and taking the time to share her experience!
