The month's results are in!
In July, my first full month selling ebooks, I vastly exceeded my goal of $200 and pulled in $473.
This month, it looks as though I'll make more, but probably only an additional $125 dollars. This month I'm rolling out a sales page, upgrading my copy on the existing listings, and deploying a promotion plan. I really think that I could leverage these books far more - I see other people who've vigilantly promoted similar books doing much, much better than me (albeit on broader topics). I'm satsfied with my results with the very little promomtion I have done, but once I have an actual optimized web page to link back to, I think the results will be quite incredible.
