More on royalties
For the new folks coming over from the PA boards, here's some more info on the way royalties work in the publishing world.
Legitimate publishers pay royalties on the cover or list price of the book, not on the "net price," not on the "sales price," not on the "discount price."
That is, if PA were a legitimate press, if you were getting an 8% royalty (which, honestly, is on the low side) and if it were figured the way the rest of the publishing industry figures royalties, you'd get $1.60 for every one of your $19.95 books that sold, regardless of what price the bookstore got 'em for, or sold 'em at.
Also, since (by definition) trade paperbacks are whole-copy returnable, one could argue that by calling their non-returnable paperbacks "trade" books, PublishAmerica is engaging in deceptive business practices and false advertising each and every time they use the term.
