Slave Labor Graphics dominates, taking the first 36 positions on the list, with perennial seller Johnny the Homicidal Maniac taking 8 of the top 10. JtHM #1 is the top seller, a comic that first came out over a decade ago.
Unfortunately Cold Cut doesn't include actual sales figures, so we can't do a long tail analysis. I assume that most comic shops that use Cold Cut are doing so because the get better service (and price?) on back issues for the non-front-of-Previews stock than they can from Diamond.
Just a reminder that the true state of the comics industry sales-wise cannot be determined by looking at Diamond's sales charts alone. The true formula is:
Total Sales = Diamond + Cold Cut (and others) + Book Market + Newsstand + Subscriptions + Direct to Consumer (online and otherwise) + Foreign Sales
Not all comics-like-things make use of all of those distribution channels; but I imagine that Slave Labor is making a good deal of their sales through places other than Diamond.
