Well, I was going to wait a little bit until I have everything sorted and time to deal with it, but I just can't wait. I made my first sale today!
I've self-published a series of fantasy novellas as eBooks (Necessary Evil). The first in the series is free, the next two are $2.99. I uploaded them to Smashwords first yesterday morning. Then I uploaded them to Amazon in the afternoon. Smashwords is immediate, but Amazon takes a while to check the books, get them listed, creates an author page, etc. And then I had to update my website with all the new links. So I wanted to wait until Amazon is all set before I announce everything to the world.
But apparently I didn't have to. In the first twenty-four hours I've had about 70 free downloads at Smashwords (Amazon doesn't let you set the price to free, but they hopefully will match the free price at Smashwords sometime soon). And now I've had my first paying customer buy the second book in the series (The Cost of Life). It's only a couple bucks in my pocket, but I'll take it.
I'm going to be out of town and busy for the next couple weeks, but I expect to devote a bit of time to getting the word out on these when I can. But it's nice that the process has already started without me.
