Amazon offers Prime members Game of Thrones: The Complete First Season on Blu-ray Disc for $17 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $4.98.) That's the lowest total price we could find by $18 and the best deal we've seen for season one on Blu-ray aside from multi-season packs. It includes digital copies of each episode.
