There’s only one thing better than grabbing a good book on sale: grabbing a good book for free<\/em>. With Amazon’s big Spring Sale, you can do just that with the Buy Two, Get One Free promotion.<\/strong> The sale covers books, Blu-rays, and more, letting you save on your favorite paperbacks and box sets. We’ve listed some of our top recommendations below. To get the discount, just add three eligible items to your basket. The price of the lowest-priced item will be deducted, giving you that item for free. You are not limited to one category, so you can choose items like Blu-rays and still get the discount. Plus, Spring Sale discounts apply to this promotion, so you can save and build your library before the sale ends on March 31.<\/p>\n Some of our recommendations include books adapted into movies, like Project Hail Mary. The big screen version of Andy Weir’s sci-fi book has earned rave reviews, but as usual in Hollywood, some cuts were made to the source material. The original book has a harder edge to the science, but the plot of a lone astronaut trying to save the world remains. You can also grab Andy Weir’s other sci-fi book, The Martian, which follows astronaut Mark Watney and his attempts to avoid becoming the first person to die on Mars.<\/p>\n See all deals at Amazon <\/div>\n
