No, unfortunately I don't have any statistics on that. We also don't have statistics on how many people are actually getting in their car, crossing the border, and loading up on books because they're wanting to buy it at the U.S. price.
All I can say is that the booksellers I've been talking to from across the country--not all of them, but many of them--are showing a decrease in sales. Some of that could be because their prices have dropped. And that's a good thing; publishers have been working for over a year to bring the printed price on the book down. That is being passed on to the consumer.
