More obsessive Amazon tracking reveals that at as of 4:30 PM today, Wastelands is the #1 best-selling SF anthology. Though as you’ll note from the screen capture below, Amazon’s categories aren’t very exact–the book ranked #2 is not an anthology at all, it’s a novel. Technically speaking, the #3 book isn’t an anthology either, but it’s a collection, and the category incorporates other collections, so I’ll let that slide.
