Actually, the eBook won't make any money unless there is quite a bit of volume. Sales of eBooks and paperbacks via the Whiskey Creek site pay the royalties stated in the contract, but those via "third party sales" which means anyone else's site, are "less expenses."
I've seen a Whiskey Creek royalty statement, and sales via Fictionwise pay approximately 3%, or less than twenty cents on a $5.99 download. The Whiskey Creek authors I know have reported more sales via the third party outlets, so low payments are the norm.
For the POD books, Whiskey Creek entrusts the Amazon listing and fulfillment to the printer's Amazon marketplace seller, which upprices the books and charges shipping, making a book which lists for $13.95 at the Whiskey Creek site cost over twenty dollars. Most customers won't pay that for a trade paperback book.
The only way to make back the set up fee is to buy copies at the author discount and resell them for whatever profit can be had.
