Finally, here's some more numbers comparing the dollars and units percentages for different months and years.

How do they calculate this information? It all starts at the comic book shop.

Data for Diamond’s sales charts — which include the monthly market shares and all top product charts — are compiled by Diamond Comic Distributors from a universe of over 3,500 comic book specialty shops located in North America and around the world. The account base includes brick-and-mortar comic book specialty shops, Internet merchants, and other specialty stores. Unit and dollars sales are calculated based upon orders invoiced and shipped to Diamond accounts during January to December 2013, which comprises initial pre-orders, advance reorders, and reorders, minus any copies that are received back from a title marked as returnable.

What are your thoughts on all these numbers? What's your predictions for this month?
