I thought I'd leave some specific information regarding the old and new versions of Fantastic Beasts and Where to Find Them, in hopes that it might be useful to some who haven't seen the original book.
You can buy the 2009 version of Fantastic Beasts and Where to Find Them at Amazon (US) via third party sellers as of this writing on 19.01.17, for $4.32. There is also a version dated June 30, 2015. Also, a version from December 4, 2008 for $8.22 for the hardcover version, available directly from Amazon (US). There are a variety of versions dated in 2016.
The new Fantastic Beasts and Where to Find Them is due out on March 14, 2017, and is currently available for pre-order at Amazon (US) for $6.99 for the Kindle and $7.38 for the hardback edition. Amazon doesn't charge your account until the book ships.
I've pre-ordered the new Hogwarts Library from Amazon (US), which will include the new Fantastic Beasts and Where to Find Them, as well as Quidditch Through the Ages and Tales of Beedle the Bard, for $23.38. It's a nice looking set and is also due out on March 14, 2017.
So, yeah, there's a few links that might be helpful!
