Upgrade Policy
If you've purchased an older edition of a book, O'Reilly will give you a 40% discount on the purchase price of the newer edition.
When you register your O'Reilly book, we'll send you an email announcement when we publish a new edition of that book. The email will include a 40% upgrade discount offer so you can purchase the new edition at 40% off directly from oreilly.com.
If you have a book dating back more than one edition, please register your book then contact Customer Service.
This upgrade policy only applies to books shipped to US addresses.
