National Parks Humble Bundle Pay What You Want ($15+ gets you everything)

If you are a fan of all things National Parks, and like to receive DRM-free eBooks, then you may want to check out the National Parks Humble Bundle. Running until next Monday mid-day (seven days from blog-posting date), you can pay anything you want, starting at $1 and receive National Parks related e-books. $1+ gets you five ebooks, $8+ gets you seven more, while $15+ gets you another seven, for a total of 19 ebooks. These are offered by Lonely Planet. The ebooks are DRM-Free, and are available to download in a variety of formats, so you can read them on any of the mainstream platforms. You can also donate a portion of your purchase towards a charity.
