A few years ago, I submitted my novel (actually it was the first draft, but that's another story) to DNA Press. I received a call from Alexander Kuklin from that publisher who liked my story. He said DNA was a small press so he didn't pay advances, but he paid 40% royalites. (I don't know if it was net, gross, wholesale, or retail -- I was too green to ask.) However, he never asked for any up-front payments.
Anyway, the deal fell through and I forgot about it. But yesterday I received a letter from him again. He remembered my book and thought he would be interested in publishing it. Of course, he has changed his business model. Now, in addition to traditional publishing, he has added subsidy publishing where I (or a sponsor (?)) could pay $3800 to have the book published. Naturally he was offering me the latter. It sounds like another small publisher gone over to the Dark Side.
After a few months here, I'm not even tempted to do this, but I wonder if anyone else has dealt with them or know anything about them. Also, I don't see anything about them on Preditors & Editors or Writer Beware.
Their website http://www.dnapress.com does seem to have published titles.
