Best Buy cuts 50% off a selection of Blizzard games for Windows and Mac, with prices starting at $9.99. (Amazon is currently price matching many of these titles.) Although we saw a similar selection of downloadable versions marked up to 75% off in November, this is still among the best deals we've seen for these games. Opt for in-store pickup to dodge shipping fees, which start at $2.99. (You can also spend $35 or more to bag free shipping.) Choose from titles like World of Warcraft, StarCraft II: Wings of Liberty, Diablo III (also available for PlayStation 3 and Xbox 360), and more.
