It doesn't matter. The ebook publisher should match the lowest available rate to buy the book.
Faced with a choice to buy a $12.99 ebook or a $7.99 pbook, if I absolutely had to buy the book, I'd go for the pbook. So, not only have I not bought the ebook, the ebook publisher has permanently lost a sale to a rival publisher. What's better, $7.99 or $0??
Of course, in reality I have such reading backlog, that I won't buy the book at all. And the OP mentioned it was the first in a series, so now I'm not buying the rest of the series either.
