Well, apparently, Lulu.com is listing my books on Amazon.com at a slight mark-up. I believe it is some sort of promotional campaign to encourage more exposure (and possibly more sales) on those who haven't opted for full distribution packages. In esssence, by having the book listed on Amazon, I'm making them more accessible to people who don't know about Lulu's marketplace. This was offered for free.
I checked Amazon and they were there. The only issue I found was that one of my books wasn't listed while the other was missing its cover image. Notably, the book Brent wrote and which I co-authored/designed had its cover image intact.
I hope this lasts because it would be a real boon to potential sales on projects that I have.
