And here's my updated report across all platforms:
February: 12 copies
March Sales: 43 copies
April Sales: 377 copies
May Sales: 273 copies
That's a drop of over 100 copies since last month. Here's the handy dandy graph (the different colours match different books...DUST is the blue book):
All in all I'm happy with the sales. April was a bit of an anomaly because DUST had several mentions in influential kindle websites and that really affected sales. I still hope that the book will, over time find traction on its own (and my other books, of course). Plus I think the YA/Kids market is still a year away from reaching its true potential. I am pleased that I now have an account with Barnes and Noble, so my books can be bought and read on the Nook (love the app for my iPad). The Nook market isn't as big as Kindle, but it's the second largest of all the markets. Plus they have a really easy interface for keeping track of your books and sales.
Update over. Art out.
