Can I sell my book on other sites or stores while it is published on Magicblox?

Absolutely.  You own the complete rights to your content and you can do whatever you want with it.  Magicblox is just one of many distribution channels for you to get your book exposed to children's book parents and readers.   However, we hope that you see the value in our service and use Magicblox as a means to promote and share your book with a wider audience.
