The Diamond Comics Advance Reorder List is a great speculator tool. It shows what books retailers are going back to get more of, in advance of their release. They are actually putting their money up betting these books get big. These are the books people are talking about in shops, message boards, and websites. Here is the Diamond Comics Advance for 11/20/16:
