Walmart offers The 100: The Complete First Season on Blu-ray and Digital HD for $12.96. (Amazon has it for the same price exclusively for Prime members.) Choose in-store pickup to dodge the $4.97 shipping fee. That's the lowest price we could find by $15. This 3-disc set includes all 13 episodes of the first season, behind-the-scenes featurettes, deleted scenes, commentaries, and other special features.
