Best Buy via eBay offers Diablo III: Reaper of Souls Collector's Edition for Windows and Mac for $43.99 with free shipping. That's the lowest total price we could find by $30, although we saw it for $24 less last fall. It includes the Diablo III: Reaper of Souls expansion pack, behind-the-scenes Blu-ray/DVD two-disc set, Reaper of Souls soundtrack, hardback artbook, mouse pad, and in-game items for Diablo III, World of Warcraft, and StarCraft II.
