Both titles submitted to CreateSpace are now available through the CS storefronts. Supposedly it takes about 15-20 days for those to go active within Amazon's search listing. I'll wait and see.
I have gone with letting Lulu.com publish and distribuate one title from them while the others are available through Lulu's general marketplace. There are multiple versions of Celtic Evil, including a larger size, a 6x9 size and a 6x9 hardcover edition.
I have come to understand that the markup prices will probably make it hard to sell and will probably just purchase copies myself at cost when anyone wants one.
