@pixelpaperyarn I've put some stuff on Smashwords that was eligible for their 'extended reach' distribution which pushes ebooks to places like the istore, Barnes and Noble, etc. With zero promotion from me a few of them sell every month. They're really cheap, small things, so I don't make more than about $10 a month from there, but they definitely get sales.
@WelshPixie thanks for the feedback!
hmm. i might check out smashwords again. last time i looked at them their formatting restrictions were super strict and didn't work with my production flow. but it might solve some of my distribution problems.
