How does a book go to three printings in the first week? Is the second additional printing for international markets? That's the only reason I can think of. DC already had sales data and orders after the first day, I don't know why they'd need to go back again so quickly.
Sales data will be neat for the book, at least. Diamond Predix: #1 of August, 167,000 buys. #whatever of September, 43,000 buys.
