A Whole Lot of Nauti

I came across Lora Leigh's Nauti Dreams is in the NCP bargain bin for $11.99, although Leigh is obviously not one of their authors.

On Amazon the same title is listed simultaneously from Berkley ($9.61) and the Jove Imprint ($7.99). All listed as "in stock".

So the NCP bargain bin is... what exactly? Just an etailer? Just conveniently not listing the publisher of the books? [Confused].
