Basically, if you format your book pretty well then it gets classed as premium and this means it will automatically get shipped to half a dozen retailers without you having to do anything.
I'm very pleased (and relieved) to say that Bane of Souls now has premium status. In a few days to a week I think it'll be shipped to other stores and hopefully become available at them shortly thereafter.
As has been noted, there seems now to be a slight issue/delay with Amazon, which is why I'm planning on publishing there directly as well, but it's still a fantastic feature.
I can't say for certain when the direct Amazon upload will happen, but if I can I'll try and make some progress over the weekend. The formatting is very slightly different to the Smashwords method but similar enough that already having the Smashwords version cut down on my workload quite a lot.
After the Amazon version is up I'll mostly return to working on Altmortis. It'll be nice to get back to writing.
