Seeing as how there's been no one who's surfaced to say they've recouped their fee, I want to know why you're even taking the trouble with these guys. Even if they're not asking money from you, they're asking money from others - and likely getting it. Which tells me they're incapable of operating like the commercial houses, and that's not someone you want handling your book.
Publishers pay you. Publishers invest in you. There's no reason for them to ever ask you for money, because they're more than capable of making it themselves. That's how they stay in business.
I certainly agree with you. It's little trouble to send stuff via e-mail. Thought I'd play along and let you all know what this place offers. There is no way I am paying one red cent to them or others.
