I'm having a hard time figuring out what you paid for... were you trying to get your poetry published, or just buying the book? If you were trying to get your poetry published, it's WAY more expensive than $15.

These guys have been reported all over the web as being a scam. There doesn't even seem to be any way to purchase any of the alleged ten anthologies they've published. They aren't publishers, they are a printer. Hopefully, you're only out $15 for one book, instead of the hundreds they're asking for to get "published", by which they mean, just do a printing run of your book.
