You'll need to be pretty quick, though, as the offer, which is to coincide with the 38th anniversary of the original NES title, is only applicable until 9th August at 11:59pm PT (so that's 10th August at 07:59am BST for those in the UK).
Simply use the promo code ZEBES at the checkout to apply the discount.
As a reminder from last time, the book contains 94 full-color pages and features gorgeous pixel art from over 125 talented artists. You've also got interviews, tutorials, feature pieces, and more to enjoy while we await more information on the upcoming Metroid Prime 4: Beyond.
Of course, if you do happen to enjoy the eBook, then the site also offers a physical edition for £20.
