As in it's non existent! I've sent four emails since my order arrived, which was for the other Hardcover version of this book, which has since, magically disappeared from their listings.
This series is amazing and I can't recommend it enough, but that's all I'll say about it, until I hear back from Top Cow Store.
Even though when I placed my order, by clicking on that cover, verifying it was the correct cover and hitting the buy button, again confirming it was the correct cover before hit submit, I was sent the wrong cover.
Maybe this will finally get their attention, I'll keep summiting these until I get a response from them. Because they list no way to contact them aside from two emails, both of which I've emailed and have received no response.
