Great free gift idea for someone who has this book!
Freakonomics was published in 2005 and spent more than 2 years on the N.Y. Times best-seller list, selling over 3 million copies worldwide, in over 30 languages.
You can get your copy of Freakonomics signed by the authors, Steven D. Levitt and Stephen J. Dubner, without shipping your copy of the book to them. Here's a simple but nicely designed sticker that the two authors can sign and mail to you, to be placed inside your book (or anywhere you want), like one of those old "ex libris" stickers. They'll even pay the postage. If you'd like a signed bookplate, just fill out the form.
You'll get a confirming email. To complete the bookplate request, please follow the instructions provided in the email to activate.
